A gas turbine power plant uses solar energy as the source of heat addition (see Figure for detailed setup and operating data).

A gas turbine power plant usessolar energy as the source ofheat addition (see Figure fordetailed setup and operatingdata). Modelling the cycle as aBrayton cycle and assuming nopressure drops in the heatexchanger or interconnectingpiping, determine: (a) thethermal efficiency; (b) the airmass flow rate, in kg/s, for a netpower output of 500kW.
