The power output of an ideal, open-cycle gas turbine cycle is 75 MW and its pressure ratio is 16. Air enters the compressor at 520 R and enters the turbine at 2800 R. Using variable specific heats at 1000°F: cp = 0.263 Btu/lbm-R and k = cp/cv = 1.353, find: (a) cycle thermal efficiency (b) mass flow rate of air.
