The air entering a compressor with a pressure ratio of 10 at 100kPa at 27°C leaves at 600K. It enters the turbine at a temperature of 1300 K and exits at a temperature of 800 K. Since the power of the gas turbine is 10 MW, a) Draw the T-s diagram of the cycle b) Find the amount of fluid circulating in the installation. c) Find the adiabatic efficiencies of the gas turbine and the compressor. d) Find net work Note. Assume that the specific heat of heating of the air is constant. cp=1 kj/kgC cv=07181 kj/kgC
3.24 You want to cool air from 150°C to 60°C but you cannot afford a custom-built heat exchanger. You find a used cross-flow exchanger (both fluids unmixed) in storage. It was previously used to cool 136 kg/min of NH3 vapor from 200°C to 100°C using 320 kg/min of water at 7°C; U was previously 480 W/m²K. How much air can you cool with this exchanger, using the same water supply, if U is approximately unchanged? (Actually, you would have to modify U using the methods of Chapters 6 and 7 once you had the new air flow rate, but that is beyond our present scope.)

For the same evaporator and condenser pressure, the temperature at the entrance of the compressor is -20degC, and the inlet to the expansion valve is subcooled by 5degC. Due to the wide temperature gap, it is decided to use a two-stage refrigeration system using flash gas removal and optimal intercooling operation in a flash chamber.
