Question: 2 There is a gas turbine power plant, which operates with air only. The air specific heat has a constant value of 0.25 Btu/lbm ."R. The pressure and temperature of the air at inlet of the compressor are 15 psia and 55 "F respectively. The maximum temperature of the cycle is 1810 "F. The pressure ratio and isentropic efficiencies for the compressor and turbine are same and have the values of 7 and 0.80 respectively, A regenerator is used in the power plant and its effectiveness is 75%. Solve and determine the following: a. All temperatures around the cycle in "F b. The efficiency of the cycle in percent c. The heat added in Btu/hr , to produce 10MW power d. The efficiency of the cycle without regenerator
