From the question above, :Width of the channel = 4 m

Depth of the flow = 2 m

Discharge = 20 m³/sec

Change in channel width = 1 mAs the discharge is constant, we have the equation of continuity as;

Q = A₁V₁ = A₂V₂

Where,Q = Discharge in m³/s

V₁ = Velocity of fluid in the original channel

A₁ = Area of the flow in the original channel

V₂ = Velocity of fluid in the new channel

A₂ = Area of the flow in the new channel

As the channel is rectangular in shape, we can write the equation as;

Q = W₁ * D₁ * V₁ = W₂ * D₂ * V₂

Where, D₁ = D₂ = D (Depth of flow)

W₁ = 4 m

W₂ = 4 + 1 = 5 m

V₁ = Velocity of fluid in the original channel

V₂ = Velocity of fluid in the new channel∴

4 * 2 * V₁ = 5 * D₂ * V₂∴ 8V₁ = 5D₂V₂∴ V₂ = 8/5 * V₁

The velocity of fluid in the new channel = 1.6V₁

Type of flow in the original channel can be determined using the Froude number as;

Fr = V₁/ √gD

Where g is the acceleration due to gravity

Fr₁ = V₁/ √gD = V₁/ √(9.81 * 2) = V₁/ 4.429

Fr₂ = V₂/ √ gD = (1.6V₁)/ √(9.81 * 2) = 1.6V₁/ 4.429

Fr₁ = V₁/ √gD = V₁/ 4.429

Fr₂ = 1.6V₁/ 4.429

Fr₁ < 1 → Subcritical flow

Fr₂ < 1 → Subcritical flow

As the value of Fr is less than 1, the type of flow is Subcritical flow

.Change in depth of the flow;

D₂ - D₁ = (W₁/W₂ - 1) * D₁D₂ - 2 = (4/5 - 1) * 2

D₂ - 2 = -0.4∴ D₂ = 1.6 m

Change in depth of the flow = D₂ - D₁ = 1.6 - 2 = -0.4 mA

B) 76.518 newtons

C) 111.834 newtons

Explanation:

A) \(F_g=\dfrac{GM_1M_2}{r^2}\) , where G is the universal gravitational constant, M 1 and 2 are the masses of both objects in kilograms, and r is the radius in meters. Plugging in the given numbers, you get:

\(F_g=\dfrac{(6.67408 \times 10^{-11})(7.8)(11.4)}{(0.8)^2}\approx 9.273 \times 10^{-9}\)

B) You can find the weight of each object on Earth because you know the approximate acceleration due to gravity is 9.81m/s^2. Multiplying this by the mass of each object, you get a weight for the first particle of 76.518 newtons.

C) You can do a similar thing to the previous particle and find that its weight is 11.4*9.81=111.834 newtons.

A) The ultimate BOD just upstream of the discharge point is determined using the formula:

BOD = DOu - DOw

Given:

DOu = 8.5 mg/L

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Answer:

The molecular weight of the gas mixture is 35.38 g/mol.

Explanation:

The molecular weight of the gas can be found using the following equation:

\( M = \frac{m}{n} \)

Where:

m: is the mass = 230 g

n: is the number of moles

First, we need to find the number of moles using Ideal Gas Law:

\( PV = nRT \)

Where:

P: is the pressure = 135 psi

V: is the volume = 15 L

R: is the gas constant = 0.082 L*atm/(K*mol)

T: is the temperature = 465 °R (K = R*5/9)

\(n = \frac{PV}{RT} = \frac{135 psi*\frac{1 atm}{14.6959 psi}*15 L}{0.082 L*atm/(K*mol)*465*(5/9) K} = 6.50 moles\)                

Finally, the molecular weight of the gas is:

\( M = \frac{m}{n} = \frac{230 g}{6.50 moles} = 35.38 g/mol \)

Therefore, the molecular weight of the gas mixture is 35.38 g/mol.

Using the Newton's second law of motion we will see that the acceleration is  0.0875 m/s^2.

The acceleration of a vehicle is determined by the force acting on it and its mass, as described by Newton's second law of motion:

F = m * a

where F is the force acting on the object, m is the mass of the object, and a is the resulting acceleration.

In this case, the force acting on the vehicle is 0.07 N, and the mass of the vehicle is 0.8 kg. Substituting these values into the equation above, we get:

0.07 N = 0.8 kg * a

Solving for a, we get:

a = 0.07 N / 0.8 kg

a = 0.0875 m/s^2

Therefore, the acceleration of the 0.8 kg vehicle powered by 0.07 N of force is 0.0875 m/s^2.

Answer:

a) the output voltage is 50 V

b)

- the average inductor current is 10 A

- the maximum inductor current is 13 A

- the maximum inductor current is 7 A

c) the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components is 4 A

Explanation:

Given the data in the question;

a) the output voltage

V₀ = V\(_s\)/( 1 - D )

given that; V\(_s\) = 20 V, D = 0.6

we substitute

V₀ = 20 / ( 1 - 0.6 )

V₀ = 20 / 0.4

V₀ = 50 V

Therefore, the output voltage is 50 V

b)

- the average inductor current

\(I_L\) = V\(_s\) / ( 1 - D )²R

given that R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6

we substitute

\(I_L\) = 20 / (( 1 - 0.6 )² × 12.5)

\(I_L\) = 20 / (( 0.4)² × 12.5)

\(I_L\) = 20 / ( 0.16 × 12.5 )

\(I_L\) = 20 / 2

\(I_L\) = 10 A

Therefore, the average inductor current is 10 A

- the maximum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] + [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmax\) = [20 / (( 1 - 0.6 )² × 12.5)] + [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmax\) = [20 / 2 ] + [ 60 / 20 ]    

\(I_{Lmax\) = 10 + 3

\(I_{Lmax\) = 13 A

Therefore, the maximum inductor current is 13 A

- The minimum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] - [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmin\) = [20 / (( 1 - 0.6 )² × 12.5)] - [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmin\) = [20 / 2 ] -[ 60 / 20 ]    

\(I_{Lmin\) = 10 - 3

\(I_{Lmin\)  = 7 A

Therefore, the maximum inductor current is 7 A

c)  the output voltage ripple

ΔV₀/V₀ = D/RCf

given that; R = 12.5 Ω, C = 40 μF = 40 × 10⁻⁶ F, D = 0.6, f = 200 Khz = 2 × 10⁵ Hz

we substitute

ΔV₀/V₀ = 0.6 / (12.5 × (40 × 10⁻⁶) × (2 × 10⁵) )

ΔV₀/V₀ = 0.6 / 100

ΔV₀/V₀ = 0.006 or 0.6%V₀

Therefore, the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components;

under ideal components; diode current = output current

hence the diode current will be;

\(I_D\) = V₀/R

as V₀ = 50 V and R = 12.5 Ω

we substitute

\(I_D\) = 50 / 12.5

\(I_D\) = 4 A

Therefore, the average current in the diode under ideal components is 4 A

The C assignment statement "9 = h + A[6]" is invalid syntax, as it attempts to assign a value to the constant 9.

It is likely that the intent was to assign the sum of the value in the variable h and the value of the element at index 6 of the array A to some other variable.

To do so, a valid variable name must be used on the left-hand side of the assignment operator. Assuming that variable is named result, the corrected statement would be "result = h + A[6];".

As such, the risk register has six components, including the risk description, risk cause, impact, risk likelihood, risk impact, and risk ranking.The following are six potential hazards for Project A and their explanations:

1. Weather Issues: Bad weather can slow down the construction process, make it dangerous to work outside, or damage materials.

2. Availability of Materials: If materials are scarce, it can delay or halt the construction project.

3. Time Constraints: Limited time can result in project delays or cutting corners, which can impact the quality of work.

4. Cost Overruns: Unexpected or uncontrollable costs can result in the project being halted or completed poorly.

5. Inadequate or Faulty Tools: This can affect work quality, safety, and efficiency, ultimately impacting the project schedule and costs.

6. Safety Issues: Inadequate safety protocols can result in accidents that could lead to injury or death of workers on the site.In conclusion, the risk register for Project A should outline potential hazards, their causes, impact, likelihood, and ranking, as well as mitigation strategies. The risk register should be reviewed and updated regularly to ensure that new risks are identified and addressed.
