A combined gas turbine-vapor power plant has a net power output of 100 MW. Air enters the compressor of the gas turbine at 100kPa, 300K, and is compressed to 1200kPa. The isentropic efficiency of the compressor is 84%. The conditions at the inlet to the turbine are 1200kPa and 1400 K. Air expands through the turbine, which has an isentropic efficiency of 88%, to a pressure of 100kPa. The air then passes through the interconnecting heat exchanger, and is finally...

Design a small gas turbine engine to produce 150 kW of net power. Use an air-standard analysis (constant gas properties) and assume air enters the compressor at 100kPa and 20°C. The compressor pressure ratio is 8, the maximum cycle temperature is 800°C, and the cold air stream leaves the regenerator 10°C cooler than the hot air stream at the inlet of the regenerator. Assume a compressor isentropic efficiency of 87% and a turbine isentropic efficiency of 93%. Determine the rates...

An air refrigeration plant of 70.26 kW, capacity comprises a centrifugal compressor, a cooler heat exchanger and an air turbine. The compressor is coupled directly to the air turbine. The compressor also receives power from another prime mover. The processes in the compressor and the turbine are adiabatic but not isentropic. Air at temperature 294 K and 85 kPa enters the compressor. It leaves the compressor at 363 K. the same air enters the turbine at 311 K and 150...

Problem 1 (Marks 3) Smithfield power station in NSW, Australia operates on 4 gas turbines. Each of the gas turbine unit operates on the regenerative Brayton Cycle between the pressure limits of 100 kPa and 700 kPa. Air enters the compressor at 30°C at a rate of 12.6 kg/s and leaves at 260°C. It is then heated in a regenerator to 400°C by hot combustion gases leaving the turbine. Diesel fuel with heating value of 42,000 kJ/kg is burned in...

In a gas turbine power plant, the gas enters the five-stage compressor at 300 K. The overall power ratio is 20. After the compression, the gas enters a regenerator with an effectiveness of 80%. For preheating, it is further heated in a combustion chamber until it reaches a temperature of 1600 K. The heated gas expands to the first turbine stage and is reheated to 1550 K. The temperatures after the reheating processes are...
