Air at 1 bar, 295 K, and a mass flow rate of 0.7 kg/s enters a compressor operating at steady state and exits at 3 bar. During the compressing from inlet to exit, the air experiences a polytropic process as PV^n=constant. m=6, n=1.48


(1) Determine the power required by the compressor.

(2) Determine the heat transfer between the compressor and the surrounding.

(s) Determine the rate of exergy destruction. Kinetic and potential energy effects are negligible. Let T_0 = 300 K ºC, P_0 = 1 bar.

(Please treat the air as ideal gas with cp=1.001 kJ/kg?K and cv=0.714 kJ/kg?K)

Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c...
