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.
