A power plant using a gas turbine operated according to the ideal Brayton cycle simply use air as the working fluid. Air enters the compressor at a pressure of 120 kPa and temperature of 290 K, then enters the turbine at a pressure of 1000 kPa and a temperature of 1100 K. Heat is transferred to air goes through a combustion process (Qin) at a rate of 42,000 kJ/sec. How much net work is given by this power plant? Assumptions: air is considered an ideal gas with a value of k = 1.4.
