A regenerative gas turbine is planned to operate with inlet conditions of 100 kPa and 300 K, a pressure ratio of 6, a turbine inlet temperature of 1600 K, and a net power output of 150 kW. The effectiveness of the regenerator is 90% and the adiabatic efficiencies of the compressor and turbine are both 80%. Determine (a) the work of the compressor [kJ/kg], (b) the heat addition [kJ/kg], (c) the back work ratio, (d) the mass flow rate of the working fluid [kg/minute], (e) the thermodynamic efficiency [%].
