translate:A gas intended for use on a small military ship with a power capacity of 320 hp in the figure A diagram of the turbine engine power plant is given. Air is the power that generates the mechanical power needed by the ship. pass through the turbine. The gas turbine engine uses diesel fuel with a thermal value of 48000 kJ / kg. Combustion In the room, you can get the Air-Fuel ratio of 75 (H / Y = 70). Omit pressure losses in heat exchangers. Model the air by getting the ideal gas as the surrounding work fluid. Taking into account the information given on the figure, (a) determine the efficiency of the engine and the fuel consumption rate, (b) fulfill duties during the 10-day duty period determine the mass of fuel that should be on board, (c) the total mass of the system (fuel and regenerator as the sum of its mass). Total mass, a function of regenerator approach temperature difference draw as. The approach temperature difference is a certain value that minimizes the total mass of the system. You should see; explain why this minimum value occurred

4-23 After heat treatment, the 2-cm thick metal plates (k = 180 W/m·K, ρ = 2800 kg/m3, and cp

= 880 J/kg·K) are conveyed through a cooling chamber with a length of 10 m. The plates enter the cooling

chamber at an initial temperature of 500°C. The cooling chamber maintains a temperature of 10°C, and

the convection heat transfer coefficient is given as a function of the air velocity blowing over the plates h

= 33V0.8, where h is in W/m2·K and V is in m/s. To prevent any incident of thermal burn, it is necessary

for the plates to exit the cooling chamber at a temperature below 50°C. In designing the cooling process to

meet this safety criteria, use the EES (or other) software to investigate the effect of the air velocity on the

temperature of the plates at the exit of the cooling chamber. Let the air velocity vary from 0 to 40 m/s, and

plot the temperatures of the plates exiting the cooling chamber as a function of air velocity at the moving

plate speed of 2, 5, and 8 cm/s.

10 kg of gaseous oxygen is compressed in a piston-cylinder device from an initial state of 0.8 m^3/kg, 25 C to a final state of 0.1 m^3/kg, 287 C, with all heat transfer taking place with the surroundings at 25 C. If the process is reversible, determine:

a) the work done in the process;

b) the overall heat transfer to the oxygen; and

c) the change in entropy of the oxygen and of the surroundings

You have just been hired by Innoson Vehicle Manufacturing to design a new sports car
whose aerodynamics is to be tested in wind tunnel. The drag force FD on the sports car
is a function of its velocity V⃗ , its projected area A into the wind, and the density ρ and
viscosity μ of air. Determine the dimensionless relationship between FD and the other

The air in a building is to be maintained at 25°C dry bulb temperature and 60% relative humidity when the outside conditions are 35°C, 50% saturation with a barometric pressure of 101.3 kPa. The total heat gains to the room are 15 kW sensible heat and 3 kW latent heat. There is no recirculation and the fresh air passes over a cooling coil to dehumidify it, and then a heater before entering the room. The cooling coil by pass factor is 0.18; the volume flow of fresh air is 5m³/s. Calculate (a) the temperature of the air leaving the cooling coil; (b) the refrigeration load for the coil in kW; (c) the heat supplied in the heater in kW.
