Air expands through a turbine operating at steady state. At the
inlet, p1 = 150 lbf/in.2,
T1 = 1400°R, and at the exit,
p2 = 14.8 lbf/in.2,
T2 = 900°R. The mass flow rate of air entering
the turbine is 11 lb/s, and 65,000 Btu/h of energy is rejected by
heat transfer.
Neglecting kinetic and potential energy effects, determine the
power developed, in hp.
