A turbine consumes 9.08 kg of air per second with a pressure ratio of 4/1. Assuming that the efficiency of the generator is 70%, that the individual performances of the turbine and compressor are 87%, that the average specific heat is constant and equal to 0.25 for both air and gases, and neglecting mechanical losses , find (a) the inlet and outlet temperatures of the air in the regenerator; (b) ditto of the gases, and (c) the average temperature difference. Absolute inlet pressure = 1,029 bar; inlet temperature = 15.6 oC, and inlet temperature to the turbine = 871 oC.
