Air enters the compressor of a simple gas turbine at p1= 14 lbf/in.2, t1 = 520degreer, and a volumetric flow rate of 10,000 ft3 / min. the isentropic efficiencies of the compressor and turbine are 83% and 87%, respectively. the compressor pressure ratio is 14 and the temperature at the turbine inlet is 2500 r. on the basis of an air-standard (not cold air-standard) analysis, calculate the thermal efficiency of the cycle. the net power developed, in btu/h.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
