The correct answer is To determine the volume flow rate and whether the flow is subcritical or supercritical, we need to calculate the Froude number (Fr) first:Fr = v / sqrt(gD)

where v is the average velocity, g is the acceleration due to gravity, and D is the hydraulic depth of the channel.The hydraulic depth can be calculated as:D = A / Pwhere A is the cross-sectional area of the flow and P is the wetted perimeter.For a half-full circular channel, we have:A = (pi/4) * D^2 = (pi/4) * (0.5*50cm)^2 = 981.75 cm^2P = pi * D = pi * 50 cm = 157.08 cmTherefore,D = A / P = 6.244 cmNow we can calculate the Froude number:Fr = 4.3 m/s / sqrt(9.81 m/s^2 * 0.06244 m) = 2.40Since the Froude number is greater than 1, the flow is supercritical.The volume flow rate (Q) can be calculated as:Q = A * v = 981.75 cm^2 * 4.3 m/s = 42,135 cm^3/s = 42.135 L/sTherefore, the volume flow rate is 42.135 L/s and the flow is supercritical.

Answer:

True.

Explanation:

True. A compressor is considered to be the "heart of the air conditioning system." It plays a vital role in the refrigeration cycle by compressing refrigerant and raising its pressure and temperature, which is essential for the cooling process.

False. In a turbojet or turbofan jet engine, each stage of the engine makes a positive contribution to total thrust

In a turbojet or turbofan jet engine, not every stage makes a positive contribution to total thrust. In fact, some stages may even contribute to drag.

The main source of thrust in a turbojet or turbofan engine comes from the combustion chamber and the expansion of high-velocity exhaust gases. The stages that play a crucial role in generating thrust include the compressor stages, combustion chamber, and turbine stages. The compressor stages compress incoming air, increasing its pressure and temperature. The combustion chamber then mixes fuel with the compressed air, ignites it, and generates high-velocity exhaust gases. Finally, the turbine stages extract energy from the high-velocity gases to power the compressor and other engine accessories.

However, there are other stages in the engine, such as inlet guide vanes, stators, and diffusers, which do not directly contribute to thrust generation. Instead, they assist in the overall functioning of the engine by improving efficiency, enhancing airflow, or reducing noise. These stages may create some additional drag or resistance to the airflow, but their primary purpose is not to generate thrust.

To determine the complex power, power factor, real power, reactive power, and apparent power for the load in the figure, we need to use the following formulas:

Complex Power = Vrms * Irms*
Power Factor = Real Power / Apparent Power
Real Power = Vrms * Irms * cos(θ)
Reactive Power = Vrms * Irms * sin(θ)
Apparent Power = Vrms * Irms

Based on the figure, we can see that the voltage and current are out of phase, which means the load is either inductive or capacitive. To determine which one, we need to calculate the phase angle θ using the following formula:

θ = acos(PF)

Where PF is the power factor.

Given that Vrms = 120V and Irms* = 2A, we can calculate the complex power as:

S = 120 * 2* = 240 VA

Next, we can calculate the power factor as:

PF = Real Power / Apparent Power = 180 / 240 = 0.75

Using this value, we can calculate the phase angle θ as:

θ = acos(0.75) = 41.4°

Now we can calculate the real power, reactive power, and apparent power as follows:

Real Power = Vrms * Irms * cos(θ) = 120 * 2 * cos(41.4°) = 90 W
Reactive Power = Vrms * Irms * sin(θ) = 120 * 2 * sin(41.4°) = 120 W
Apparent Power = Vrms * Irms = 120 * 2 = 240 VA

Therefore, the load is capacitive since the reactive power is positive.

Effective stress is the stress that is transmitted between soil particles, and is important for calculating the amount of skin friction developed along the length of driven piles. To calculate the effective stress at a depth of 5 m, we need to consider the weight of the soil above the depth of interest and the weight of the water above the soil. For low tide conditions, the water level is 2 m below the ground surface, so the effective stress at 5 m depth would be the unit weight of the sand multiplied by the depth of soil above it, which is 5 m. Thus, the effective stress at 5 m depth would be 95 kPa (19 kN/[tex]m^3[/tex]x 5 m).

For high tide conditions, the water level is 2 m above the ground surface, so we need to consider the weight of the water as well. The weight of the water above the 5 m depth of soil is (2 m x 9.81 kN/[tex]m^3[/tex]), which is 19.62 kN/[tex]m^2[/tex]. Therefore, the effective stress at 5 m depth would be the unit weight of the sand multiplied by the depth of soil above it (5 m) minus the weight of the water above it (19.62 kN/[tex]m^2[/tex]).

Q = (1/n) * A * R^(2/3) * S^(1/2)

Where:

n = Manning's roughness coefficient

To find the best cross-sectional width, we need to choose the value of b that satisfies the flow rate and yields the minimum hydraulic radius for a given flow depth.

By trial and error, using the provided answer choices, we can determine the best width:

Option a) b = 0.48 m

Option b) b = 0.63 m

Option c) b = 0.70 m

Option d) b = 0.82 m

Option e) b = 0.97 m

Substituting these values into the equations and calculating the hydraulic radius, we can compare the results and select the option that yields the minimum hydraulic radius.
