A gas turbine power plant (Brayton cycle) operates under the following conditions with two stages of intercooling. 100 kPa, 1 MPa and 10 MPa. The inlet temperature to the first compressor is 300 K. The compressors have an isentropic efficiency of 0.68. The turbine outlet temperature is measured to be 927K. The total power generated is 70 MW while the heat added in the combustor is 120 MW. The regenerator has an efficiency of 0.82. A) Calculate the cycle efficiency, B) the mass flow rate of air (kg/s), C) and the isentropic efficiency of the turbine.
