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.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
