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.
