A new energy conversion mechine has been proposed that has two inflows of air. At one inlet port 10 kg/s enters at 10 MPa and 348K. At the other, 2 kg/s enters at 2 MPa and 1273K. there is a single air-outlet stream discharging to the atmosphere at 0.1 MPa. No fuel enters the machine, not are there any other inflows or outflows of material. The casing around the machine is well insulated, so that heat transfer between the machine and the surrounding air is negligible. Inlet and exit kinetic energy fluxes are insifnificant. What is the maximum power that the machine could produce in steady flow if the exhaust pressure were 0.1 MPa? for air r=1.4 and Cp = 1.0035 KJ/Kg-K.
