Question

An open cycle gas turbine using a regenration arrangement. The air enters the compressor at 1 bar 288 K and is compressed to 10 bar with compressor effieciency= 0.85. The air is heated in regenerator and then enter in combustion chamber its temperature is raised ny 1700 k and during the process the pressure falls by 0.2 bar. The air is then expanded in the turbine and passes to regenerator which has 0.75 effectiveness and cause a pressure drop of 0.2 bar. the isotropic turbine efficiency=0.86.

1. Draw plant dig. and TS.

2. Calculate thermal efficiency and power output at air mass flow rate=100 kg/sec
