An ideal air-standard Brayton cycle has a compressor pressure ratio of 10. Air enters the compressor at P, = 14.7 psi, T, = 70°F, with a mass flow rate of 90,000 lb/hr. The inlet temperature is 2200 R. The ideal air-standard Brayton cycle analysis is now modified to include the compressor and turbine having isentropic efficiencies of 84% and 88%, respectively. Determine for the modified cycle analysis [a] the thermal efficiency. [n = 31.3%] the net power developed, in horsepower. [WNet 3253 hp] [a]
