The temperature and pressure of an ideal gas are directly proportional

The pressure of the system should be in the range B) 94 psig

The given refrigerator parameters are;

The temperature of the system and the surrounding, T₁ = 75 °F = 237.0389 K

The pressure to which the system was charged with nitrogen, P₁ = 100 psig

The temperature to which the system dropped, T₂ = 50 °F = 283.15 K

The required parameter;

The pressure, P₂, of the system at 50°F

Method:

The relationship between pressure and temperature is given by Gay-Lussac's law as follows;

At constant volume, the pressure of a given mass of gas is directly proportional to its temperature in Kelvin

Mathematically, we have;

\(\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}\)

Plugging in the values of the variables gives;

\(\mathbf{\dfrac{100 \ psig}{297.0389}} = \dfrac{P_2}{283.15}\)

Therefore;

\(P_2 = \mathbf{283.15 \, ^{\circ}F \times \dfrac{100 \ psig}{297.0389\ ^{\circ}F} \approx 95.3 \, ^{\circ}F}\)

The closest option to the above pressure is option B) 94 psig

Answer: basically we are asked to find it's force and the formula that helps us to find force is Force= Mass× Acceleration

so let's put out the given and what we need to find

GIVEN. Solution

F=m.a

Mass= 1300. F=1300kg×20m/s

speed (Acceleration)=20m/2. F=26000Kg.m/s

Force=? F=26000N

N stands for Newton and the reason that it comes Newton is because it is the SI-unit of Force and the result of kg×m/s.

Here's the code to accomplish the task using nested for loops in C++:

#include <iostream>

using namespace std;

int main() {

   int inVal;

   int i;

   int j;

   cin >> inVal;

   for (i = 0; i <= inVal; i++) {

       for (j = 0; j < i; j++) {

           cout << "+";

       }

       cout << i << endl;

   }

   return 0;

}

Define the term nested.

Nested refers to a situation where one construct, such as a loop or conditional statement, is placed inside another construct of the same type. For example, a nested for loop is a loop within another loop, where the inner loop is executed multiple times for each iteration of the outer loop. Similarly, a nested if statement is an if statement within another if statement, where the inner if statement is only executed if the outer if statement evaluates to true. Nesting is a common programming technique used to solve complex problems by breaking them down into smaller, more manageable parts.

This program reads an integer inVal from input and then uses nested for loops to output each number from 0 to inVal, followed by a corresponding number of plus sign characters. The output for each number is ended with a newline character.

The outer for loop iterates from 0 to inVal, while the inner loop iterates from 0 to i - 1. For each iteration of the inner loop, a plus sign character is output, and after the inner loop, the current value of i is output on a new line. The number of plus sign characters output is determined by the current value of i, since the inner loop runs i times.

Therefore, the program outputs a sequence of numbers followed by a corresponding number of plus sign characters, where the number of plus sign characters for each number increases as the number increases.

The strength of the electric field between these two equipotential lines at this separation is 10 V/m.

To calculate the strength of the electric field between the 3V and 1V lines of equipotential separated by 20 cm in a certain region, we can use the formula :

E = V/d

where E is the electric field strength, V is the potential difference between the two lines, and d is the separation distance between the lines.

In this case, the potential difference is 2V (3V - 1V) and the separation distance is 20 cm (0.2 m).

Therefore, the electric field strength would be E = 2V/0.2m = 10V/m.

This means that for every meter between the 3V and 1V lines, there is an electric field strength of 10V.

Answer:

To solve this problem, we need to use the Reynolds number, the Prandtl number, and the Darcy friction factor. The Reynolds number is a dimensionless number that describes the flow regime of the fluid, the Prandtl number characterizes the ratio of momentum diffusivity to thermal diffusivity, and the Darcy friction factor describes the frictional losses in the pipe.

(a)

For pressurized water at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 997 kg/m^3 (density of water at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (997 * 0.000314) = 3.18 m/s

The Reynolds number for water is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.000283 Pa s (dynamic viscosity of water at 366 K)

Re = (997 * 3.18 * 0.02) / 0.000283 = 2.24e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 2.24e5 * 0.02 = 224 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For water at 366 K, Pr = 5.5 and we can estimate Nu using the Dittus-Boelter correlation:

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Nu = 0.023 * (2.24e5)^(4/5) * 5.5^(0.4) = 244

L_th = 0.05 * 2.24e5 * 5.5 * 0.02 / 244 = 3.6 m

For engine oil (unused) at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 890 kg/m^3 (density of engine oil at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (890 * 0.000314) = 3.79 m/s

The Reynolds number for engine oil is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.0003 Pa s (dynamic viscosity of engine oil at 366 K)

Re = (890 * 3.79 * 0.02) / 0.0003 = 4.72e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 4.72e5 * 0.02 = 472 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For engine oil at 366 K, Pr = 130 and we can estimate Nu using the Dittus-Boelter correlation:

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Nu = 0.023 * (4.72e5)^(4/5) * 130^(0.4) = 2600

L_th = 0.05 * 4.72e5 * 130 * 0.02 / 2600 = 7.2 m

For NaK (22%/78%) at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 1100 kg/m^3 (density of NaK at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (1100 * 0.000314) = 2.87 m/s

The Reynolds number for NaK is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.0018 Pa s (dynamic viscosity of NaK at 366 K)

Re = (1100 * 2.87 * 0.02) / 0.0018 = 3.48e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 3.48e5 * 0.02 = 348 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For NaK at 366 K, Pr = 0.013 and we can estimate Nu using the Sieder-Tate correlation:

Nu = 0.027 * Re^(4/5) * Pr^(0.43)

Nu = 0.027 * (3.48e5)^(4/5) * 0.013^(0.43) = 67.3

L_th = 0.05 * 3.48e5 * 0.013 * 0.02 / 67.3 = 0.008 m

(b)

For water and engine oil, the mass flow rate is given as 0.01 kg/s, and the mean velocity is given as 0.02 m/s.

For water at 300 K:

rho = 996.6 kg/m^3 (density of water at 300 K)

mu = 0.000547 Pa s (dynamic viscosity of water at 300 K)

Pr = 7.02 (Prandtl number of water at 300 K)

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Re = (rho * v * D) / mu = (996.6 * 0.02 * 0.02) / 0.000547 = 1445

Nu = 0.023 * Re^(4/5) * Pr^(0.4) = 0.023 * (1445)^(4/5) * 7.02^(0.4) = 426.5

L_hyd = 0.05 * Re * D = 0.05 * 1445 * 0.02 = 14.45 m

L_th = 0.05 * Re * Pr * D / Nu = 0.05 * 1445 * 7.02 * 0.02 / 426.5 = 0.021 m

For water at 400 K:

rho = 958.4 kg/m^3 (density of water at 400 K)

mu = 0.000294 Pa s (dynamic viscosity of water at 400 K)

Answer:

The value of \(\mathbf{BOD_5 \ at \ 15^0 \ C \ is \simeq 130.14 \ mg/L}\)

Explanation:

From the given information:

To find the BOD5 (in mg/L) at 15° C; we need to know the ultimate carbonaceous BOD and the reaction rate coefficient at  15° C.

So, to start with the calculation of the ultimate carbonaceous BOD by using the formula:

\(BOD_t = L_o (1-e^{-k*t})\)

where;

\(BOD _t\) = Biochemical oxygen demand at t days

\(L_o\) = the ultimate carbonaceous

∴

\(150= L_o (1-e^{-0.20*5})\)

\(L_o =\dfrac{150}{ (1-e^{-0.20*5})}\)

\(L_o =\dfrac{150}{ (1-0.3679)}\)

\(L_o =237.30 \ mg/L\)

Thus, the ultimate carbonaceous BOD = 237.30 mg/L

For the reaction rate coefficient; we use the formula:

\(k_{\tau} = k_{20} \times \theta^{\tau - 20}\)

where;

\(k_{\tau}\) = rate of the reaction constant at various temperature (T) = 15

\(k_{20}\) = rate of the reaction constant at standard laboratory = 0.20

\(\theta\) = constant = 1.047

∴

\(k_{15} =0.20 \times \theta^{15 - 20}\)

\(k_{15} =0.20 \times 1.047^{-5}\)

\(k_{15} =0.20 \times0.7948\)

\(k_{15} = 0.1590 / day\)

Thus, at 15° C, the reaction constant (k) = 0.1590 / day

Finally, the BOD5 (in mg/L) at 15° C can be calculated by using the formula:

\(BOD_t = L_o (1 - e^{-k*t})\)

\(BOD_t = 237.30 \times (1 - e^{-0.1590*5})\)

\(BOD_t = 237.30 \times (1 -0.45158)\)

\(BOD_t = 237.30 \times (0.54842)\)

\(\mathbf{BOD_5 \simeq 130.14 \ mg/L}\)

A.This alloy's tensile strength will be 450MPa, B. Its modulus of elasticity will be 200GPa, C. The yield strength will be 200MPa.

What is tensile strength?
Tensile strength is a measure of the maximum amount of force that can be applied to a material before it breaks. It is measured in units of force per unit area, such as pounds per square inch or newtons per square meter. Materials with high tensile strength can withstand large amounts of tension without breaking. This property is important for many applications, such as bridge construction, building materials, and aircraft components. Tensile strength is determined by performing a tensile test on a sample of the material, in which a force is applied to the material until it breaks. The results of the test are then used to calculate the ultimate tensile strength of the material.

next we will differentiate the equation to get the locus of the velocity

z = 0.2 cos2∅∅

differentiate the equation furthermore to get the locus of acceleration in the horizontal axis

z = -0.4sin2∅(∅)^2 + 0.2cos2∅∅

note : express ∅ as 6 rad.\(s^{-1}\) for angular velocity and ∅ = 0 for angular acceleration

equation above becomes :

Z = - 0.4 sin 2∅ ( 6)^2 + 0.2 cos 2∅(0)

  = - 14.4 sin 2∅ ( acceleration of the follower in horizontal direction )

next calculate The force at the end of A of the follower

Fa - Kx = mz  

note: m = w / g hence : Fa - Kx = w/g z  ------- (2)

w = weight of the spring-held follower = 0.75 Ib

x = compression of the spring = 0.4

k = spring stiffness = 12 Ib/ft

Explanation:

Transformer ratings :

Base power ( Sb ) = 50 KVA ,  

Transformer voltage = 2400 / 240 V ,  

Impedance ( Zp.u ) = 3.0 % = 0.03

phase = single ( 1 ) phase

Base Voltage on low side ( Vb ) = 240 V

a) Calculate the base current ( Ib )

Ib = Sb / Vb = ( 50 * 10^3 ) / 240

                    = 208.33 A

b) calculate base impedance ( Zb )

Zb = Vb^2 / Sb = ( 240 )^2 / 50000

                        = 1.152 Ω

c) Calculate the actual impedance ( Zact )

Zact = Zp.u * Zbase
