Air enters a jet engine through section 1 with an area of A1=0.5 m2 at a (relative) speedof 250 m/s. The pressure at the entrance is atmospheric pressure (approximately 105 Pa)and the temperature is 300 K. Inside the engine, the injected fuel mixes perfectly withair, with fuel to air mass ratio of 1:30. The enthalpy and the kinetic energy flow rate ofthe fuel can be neglected at the fuel inlet. The combustion releases a heat per unit mass(of air) of 200 kJ/kg, after which the mixture is expanded through a nozzle to the exitsection 2 whose area is A2= 0.4 m2. The product of combustion can be taken to havethe same properties of air (such as Cp=1.005 kJ/kg k, γ=1.4 and so on). The nozzleperfectly expands the flow such that at the exit 2, the pressure is atmospheric pressure.The temperature of the flow at the exit is 400 K. The figure below shows a roughschematic of the engine and the flow. Find the thrust generated by the engine.

Hot combustion gases (assumed to have the properties of air at room temperature, Cp=1.005 kJ/kg-K) enter a gas turbine at 0.8 MPa and 1500 K at a rate of 2.1 kg/s, and exit at 0.1 MPa and 800 K. If heat is lost from the turbine to the surroundings at a rate of 150 kJ/s, the power output of the gas turbine isQuestion 10Select one:a.(a) 1477 kWb.(b) 1677 kWc.(c) 1327 kWd.(d) 1124 kWe.(e) 872 kWf.Insufficient information to answer question
