At steady state, steam with a mass flow rate of 10 lb/s enters a turbine at 800°F and 600 lbf/in.2 and expands to 60 lbf/in.2 The power developed by the turbine is 2852 horsepower. The steam then passes through a counterflow heat exchanger with anegligible change in pressure, exiting at 800°F. Air enters the heat exchanger in a separate stream at 1.1 atm, 1020°F and exits at 1 atm, 620°F. Kinetic and potential energy changes can be ignored and there is no significant heat transfer between either component and its surroundings. Determine

(a) the mass flow rate of air, in lb/s.

(b) the rate of entropy production in the turbine, in Btu/s °R.
