Find total rate of entropy generation turbine-surroundings

Air at 5 bar and 177^oC (State 1) is expanded through a turbine to 1 bar and 27^oC (State2). The mass flow rate of air through the turbine is 2 kg/s. Stray heat loss of 53.22 kW occurs to a surrounding at 27?C. Assume the surface temperature of the turbine at which heat loss occurs to be the average of the inlet and exit air temperatures. Consider variable specific heats for air.

(a) Calculate the power (kW) developed by the turbine.

(b) What is the rate of entropy generation (kW/K) within the turbine?
