A gas-turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 and 1200 kPa
A gas-turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 and 1200 kPa. The working fluid is air, which enters the compressor at 300K at a rate of 150 m3/min and leaves the turbine at 773K. Using variable specific heats for air and assuming a compressor isentropic efficiency of 82 percent and a turbine isentropic efficiency of 88 percent, determine:
(a) the net power output
(b) the back work ratio
(c) the thermal efficiency
