A stationary gas turbine plant operates on the Brayton cycle and delivers 20,000 kW to an electric generator. The maximum temperature is 1200 K and the minimum temperature is 290 K. The minimum and maximum pressures are 95 and 380 kPa, respectively. Calculate :
a- The power output of the turbine.
b- The fraction of the output of the turbine which is used to drive the compressor.
c- The mass and volume flow rates at inlet to the compressor.
