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
