The channel is lined with reinforced concrete and has aManning roughness coefficient of 0.015, a horizontal slope, and merges with a river where the depth of flow is 3.5 m. Does a hydraulic jump occur in the lined channel

Answers

Answer:

hello your question is incomplete attached below is the complete question

answer: There is a hydraulic jump

Explanation:

First we have to calculate the depth of flow downstream of the gate

y1 = \(C_{c} y_{g}\) ----------- ( 1 )

Cc ( concentration coefficient ) = 0.61  ( assumed )

Yg ( depth of gate opening ) = 0.5

hence equation 1 becomes

y1 = 0.61 * 0.5 = 0.305 m

calculate the flow per unit width q

q = Q / b ----------- ( 2 )

Q = 10 m^3 /s

 b = 2 m

hence equation 2 becomes

q = 10 / 2 = 5 m^2/s

next calculate the depth before hydraulic jump y2 by using the hydraulic equation

answer : where  y1 < y2 hence a hydraulic jump occurs in the lined channel

true or false. marin factors reduce the strength and stress concentrations factors increase the stress; therefore, they both increase the safety factor.

Answers

The given statement is false because Marin factors do not reduce the strength and stress concentrations factors do not increase the stress. Instead, they both reduce the safety factor.

Marin factor is a corrosion factor that takes into account the corrosion of the material of interest. When compared to the yield strength of the material, corrosion usually reduces the yield strength of the material. Because of this, the engineering process must consider the effect of corrosion on the material being used to ensure that it does not become so degraded that it fails prematurely. Hence, the Marin factor increases the safety factor and hence reduces the likelihood of failure.

When there is a change in section or a flaw in a structural member, stress concentration occurs. This is where the stress concentration factor is used. It is used to assess the effect of these conditions on the stress levels that result. The stress concentration factor increases the maximum stress that results in the presence of stress raisers. As a result, it reduces the safety factor and makes it more likely that the structural member will fail prematurely, unlike the Marin factor.

Therefore, the statement is false because the Marin factor reduces the stress and the stress concentration factor increases the stress, and they both reduce the safety factor instead of increasing it.

Both copper and stainless steel are being considered as a wall material for a liquid cooled rocket nozzle. The cooled exterior of the wall is maintained at 150°C, while the combustion gases within the nozzle are at 2750°C. The gas side heat transfer coefficient is known to be hᵢ = 2×10⁴ W/m²-K, and the radius of the nozzle is much larger than the wall thickness. Thermal limitations dictate that the temperature of copper must not exceed 540°C, while that of the steel must not exceed 980°C. What is the maximum wall thickness that could be employed for each of the two materials? For Cu, ρ = 8933 kg/m³, k = 378 W/m-K and for stainless steel, ρ = 7900 kg/m³, k = 23.2 W/m-K

Answers

a. The maximum thickness of the copper nozzle is 3.3 mm

b. The maximum thickness of the steel nozzle is 0.054 mm

The question has to do with heat transfer

What is heat transfer?

Heat transfer is the movement of heat energy from one body to anotrher.

How to calculate the maximum wall thickness?

Since the rate of heat loss by the gas equal rate of heat gain by the metal.

Rate of heat loss by gas

The rate of heat loss by gas is P = -hA(T - T') where

h = heat transfer coefficient of gas = 2 × 10⁴ W/m²-K, A = surface area of nozzle, T = maximum temperature of metal and T = Temperature of gas = 2750°C

Rate of heat gain by metal

The rate of heat gain by metal is given by P' = kA(T - T")/t where

k = thermal coefficient of metal, A = surface area of nozzle, T = maximum temperature of metal, T" = temperature of exterior wall of nozzle = 150°C and t = thickness of nozzle.

Maximum thickness of nozzle.

Since P = P', we have that

-hA(T - T') =  kA(T - T")/t

Making t subject of the formula, we have

t = -k(T - T")/h(T - T')

a. Maximum thickness for copper nozzle

Given that for copper

T = 540°C and k = 378 W/m-K

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -378 W/m-K(540°C - 150°C)/[2 × 10⁴ W/m²-K(540°C - 2750°C)]

t = -378 W/m-K(390°C)/[2 × 10⁴ W/m²-K(-2210°C)]

t = 147420 W/m/4420 × 10⁴ W/m²

t = 147420 W/m/44200000 W/m²

t = 0.0033 m

t = 3.3 mm

So, the maximum thickness of the copper nozzle is 10.71 cm

b. Maximum thickness for steel nozzle

Given that for steel

T = 980°C and k = 23.2 W/m-K

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -23.2 W/m-K(980°C - 150°C)/[2 × 10⁴ W/m²-K(980°C - 2750°C)]

t = -23.2 W/m-K(830°C)/[2 × 10⁴ W/m²-K(-1770°C)]

t = 19256 W/m/3540 × 10⁴ W/m²

t = 19256 W/m/35400000 W/m²

t = 0.0000544 m

t = 0.0544 mm

t ≅ 0.054 mm

So, the maximum thickness of the steel nozzle is 0.054 mm

1. Purpose: Apply various algorithm design strategies to solve a problem, practice formulating and analyzing algorithms, implement an algorithm. In the US, coins are minted with denominations of 50, 25, 10, 5, and 1 cent. An algorithm for making change using the smallest possible number of coins repeatedly returns the biggest coin smaller than the amount to be changed until it is zero. For example, 17 cents will result in the series 10 cents, 5 cents, 1 cent, and 1 cent.
a) (4 points) Give a recursive algorithm that generates a similar series of coins for changing n cents. Don’t use dynamic programming for this problem.
b) (4 points) Write an O(1) (non-recursive!) algorithm to compute the number of returned coins.
c) (1 point) Show that the above greedy algorithm does not always give the minimum number of coins in a country whose denominations are 1, 6, and 10 cents.
d) (6 points) Given a set of arbitrary denominations C =(c1,...,cd), describe an algorithm that uses dynamic programming to compute the minimum number of coins required for making change. You may assume that C contains 1 cent, that all denominations are different, and that the denominations occur in in increasing order.

Answers

Answer:

Explanation:a) Recursive algorithm for generating a series of coins for changing n cents:

arduino

Copy code

function makeChange(n):

   if n == 0:

       return []

   for coin in [50, 25, 10, 5, 1]:

       if coin <= n:

           return [coin] + makeChange(n - coin)

This algorithm recursively finds the largest coin smaller than the remaining amount and adds it to the list of coins. It continues this process until the remaining amount becomes zero. The algorithm iterates through the coin denominations in descending order to prioritize using the largest possible coins first.

b) O(1) algorithm to compute the number of returned coins:

arduino

Copy code

function countCoins(n):

   count = 0

   for coin in [50, 25, 10, 5, 1]:

       count += n // coin

       n %= coin

   return count

This algorithm uses a loop to iterate through the coin denominations and counts how many times each coin can be used to change the amount. It performs integer division (//) to determine the number of coins of each denomination and updates the remaining amount (n) using the modulus operator (%). The final count represents the total number of coins used.

c) The greedy algorithm for making change does not always provide the minimum number of coins when the denominations are 1, 6, and 10 cents. A counterexample is changing 12 cents. The greedy algorithm would return 10 cents and two 1 cents, totaling three coins. However, the optimal solution is two 6 cents coins, which requires only two coins. This counterexample demonstrates that the greedy algorithm may not consider all possible combinations and can lead to suboptimal results.

d) Dynamic programming algorithm for computing the minimum number of coins required for making change with arbitrary denominations:

less

Copy code

function minCoins(denominations, amount):

   dp = [infinity] * (amount + 1)

   dp[0] = 0

   for coin in denominations:

       for i in range(coin, amount + 1):

           dp[i] = min(dp[i], dp[i - coin] + 1)

   return dp[amount]

This algorithm uses dynamic programming to solve the problem. It creates a list dp of size amount + 1 to store the minimum number of coins required for each value from 0 to the target amount. It initializes all entries in dp with infinity except for the first entry, which is set to 0. Then, it iterates through each coin denomination and updates dp by considering the minimum between the current value and the value obtained by subtracting the coin denomination and adding 1. The final result is stored in dp[amount], which represents the minimum number of coins needed to make change for the given amount using the provided denominations.

Calculate the steady state flux of atomic hydrogen at 25°C through a steel vessel of wall thickness 4 mm given that the inside surface is kept saturated with hydrogen at a concentration of 4.5 moles/m3, the outside surface is exposed to the atmosphere. (The diffusivity of hydrogen in steel D0 = 0.1 mm2 s-1, Q = 13.5 kJ mol-1) A steady-state flux allows the application of Fick’s first law: J = -D(dC/dx)
If the vessel contains 20 moles of hydrogen, calculate the time taken to dissipate all of the hydrogen of that the vessel has a surface area of 3 m2.

Answers

Answer:

To calculate the steady state flux of atomic hydrogen through a steel vessel, we need to use Fick's first law, which states that the flux (J) is equal to the diffusivity (D) multiplied by the concentration gradient (dC/dx).

First, we need to calculate the concentration gradient by dividing the difference in hydrogen concentration between the inside and outside surfaces by the wall thickness of the vessel. The inside surface is kept saturated with hydrogen at a concentration of 4.5 moles/m3, and the outside surface is exposed to the atmosphere, which has a hydrogen concentration of 0 moles/m3. Therefore, the concentration gradient is (4.5 - 0) moles/m3 / (4 mm) = 1.125 moles/m3 mm.

Next, we need to substitute this value into Fick's first law along with the diffusivity of hydrogen in steel, which is given as 0.1 mm2/s. This gives us the steady state flux as J = (-0.1 mm2/s) * (1.125 moles/m3 mm) = -0.01125 moles/s mm2.

Finally, we need to convert the units of the flux from moles/s mm2 to moles/s m2. To do this, we can multiply the flux by 1,000 to convert the units of millimeters to meters, giving us a final steady state flux of -0.01125 moles/s mm2 * 1,000 = -1.125 moles/s m2.

IF THE VESSEL CONTAINS 20 MOLES OF HYDROGEN, CALCULATE THE TIME TAKEN TO DISSIPATE ALL OF THE HYDROGEN OF THAT THE VESSEL HAS A SURFACE AREA OF 3 M2.

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm2/s, the inside concentration is 4.5 moles/m3, and the outside concentration is 0, the concentration gradient is 4.5 moles/m3.

Plugging these values into the equation above, we get:

J = -0.1 mm2/s * 4.5 moles/m3 = -0.45 moles/s-m2

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.

Explanation:

SELF EXPLANATORY

The time taken is 44.44 seconds to dissipate all of the hydrogens from the vessel.

How to calculate the time?

To solve this problem, we need to first calculate the flux of atomic hydrogen through the vessel using Fick's first law:

J = -D(dC/dx)

where J is the flux, D is the diffusivity of hydrogen in steel, and dC/dx is the concentration gradient.

Given that the diffusivity of hydrogen in steel is 0.1 mm²/s, the inside concentration is 4.5 moles/m³ and the outside concentration is 0, the concentration gradient is 4.5 moles/m³.

Plugging these values into the equation above, we get:

J = -0.1 mm²/s * 4.5 moles/m³ = -0.45 moles/s-m²

Next, we need to calculate the time it takes to dissipate all 20 moles of hydrogen from the vessel. We can do this by dividing the total number of moles of hydrogen by the flux:

t = 20 moles / (-0.45 moles/s-m2) = 44.44 s

So it would take approximately 44.44 seconds to dissipate all of the hydrogen from the vessel.

The volume of the transmitter can be neglected when compared to the balloon's size. The balloon is released from ground level and quickly reaches its terminal ascent velocity. Neglecting variations in the atmosphere's density, how long does it take the balloon to reach an altitude of 1000 ft?

Answers

Answer:

12 mins

Explanation:

The summation of the forces in vertical direction

= Fb - Fd - w = 0 ∴ Fd = Fb - w  ----- ( 1 )

Fb ( buoyant force ) = Pair * g * Vballoon ------- ( 2 )

Pair = air density , Vballoon = volume of balloon

Vballoon = \(\frac{\pi D^3}{6}\) ,  where D = 4  ∴  Vballoon = 33.51 ft^3

g = 32.2 ft/s^2

From property tables

Pair = 2.33 * 10^-3 slug/ft^3

μ ( dynamic viscosity ) = 3.8 * 10^-7 slug/ft.s

Insert values into equation 2

Fb = ( 2.33 * 10^-3 ) * ( 32.2 ) *( 33.51 )  = 2.514 Ib

∴ Fd = 2.514 - 2.5 = 0.014 Ib ( equation 1 )

Assuming that flow is Laminar  and  RE < 1

Re = (Pair * vd) / μair   -------- ( 3 )

where:  Pair = 2.33 * 10^-3 slug/ft^3 ,  vd = ( 987 * 4 ) ft^2/s ,   μair = 3.8 * 10^-7 slug/ft.s

Insert values into equation 3

Re = 2.4 * 10^7 (  this means that the assumption above is wrong )

Hence we will use drag force law

Assume Cd = 0.5

Express  Fd using the relation below

Fd = 1/2* Cd * Pair * AV^2

therefore V = 1.39 ft/s

Recalculate  Reynold's number using  v = 1.39 ft/s

Re = 34091

from the figure Cd ≈ 0.5 at Re = 34091  

Finally calculate the rise time ( time taken to reach an altitude of 1000 ft )

t = h/v

  = 1000 / 1.39 = 719 seconds ≈ 12 mins

Which of these is known as the greatest danger associated with excavations?
Select the best option.

Asphyxiation


Cave-ins


Fire


Underground utility lines

Answers

Answer:

Cave-ins

Explanation:

The term excavation means any form of cuts, depression or trench by removing the surface of the earth. This process is intended primarily for the purpose of construction and maintenance or exploration. In this process there are many hurdles that pose danger to both human life and earth. The excavation workers face the great threat because of cave-ins. The collapsing of the earth's surface and random accidents prove to be very dangerous for the workers.

a bourdon pressure gauge with a range of 0 - 150 psi is used to monitor water pressure in a manufacturing plant. the plant engineer wants to replace the bourdon gauge with a diaphragm gauge that can be monitored electronically. specify the range of pressure in kpa needed for the replacement diaphragm gauge.

Answers

To convert the range of the bourdon pressure gauge from psi to kPa, we need to multiply the psi value by 6.895. Therefore, the range of the bourdon pressure gauge in kPa is 0 - 1034.25 kPa (rounded to two decimal places).

For the replacement diaphragm gauge, we need to know the specific range of pressure required. Without that information, we cannot provide a specific answer. However, we can say that the diaphragm gauge should have a range of at least 0 - 1034.25 kPa to be equivalent to the bourdon pressure gauge that is being replaced. The engineer may choose to have a wider range depending on the specific needs of the manufacturing plant.
To convert the range of the Bourdon pressure gauge (0-150 psi) monitoring water pressure in the manufacturing plant to a range in kPa for the replacement diaphragm gauge, you need to follow these steps:
1. Convert psi to kPa: 1 psi ≈ 6.89476 kPa
2. Multiply the lower and upper limits of the range by the conversion factor.
For the lower limit (0 psi):
0 psi * 6.89476 kPa/psi = 0 kPa
For the upper limit (150 psi):
150 psi * 6.89476 kPa/psi ≈ 1034.21 kPa
Your answer: The range of pressure needed for the replacement diaphragm gauge is 0-1034.21 kPa.

To convert the range of pressure from psi to kPa, we can use the conversion factor 1 psi = 6.895 kPa. Therefore, the range of pressure for the bourdon gauge is 0-1034.25 kPa (0-150 psi x 6.895 kPa/psi).

For the replacement diaphragm gauge, we need to ensure that it has a suitable range of pressure to monitor the water pressure in the manufacturing plant. The engineer should consider the maximum and minimum pressure values that the plant experiences and select a diaphragm gauge that has a range that encompasses these values.Assuming that the maximum and minimum pressure values in the manufacturing plant are within the range of the bourdon gauge, we can use the same range for the replacement diaphragm gauge. Therefore, the range of pressure for the replacement diaphragm gauge would be 0-1034.25 kPa. However, if the maximum and minimum pressure values in the manufacturing plant exceed the range of the bourdon gauge, the engineer would need to select a diaphragm gauge with a larger range of pressure. They could consult with a supplier or manufacturer to determine the appropriate range of pressure for the replacement diaphragm gauge. In any case, the engineer should ensure that the diaphragm gauge they select is compatible with electronic monitoring and can provide accurate and reliable measurements of the water pressure in the manufacturing plant.
