Regeneration, Reheat, and Compression with Intercooling
An air-standard Brayton cycle has a compressor pressure ratio of 10. Air enters the compressor at p1 = 14.7 lbf/in.2, T1 = 70°F with a mass flow rate of 90,000 lb/h. The turbine inlet temperature is 2200°R. Calculate the thermal efficiency and the net power developed, in horsepower, if
(a) the turbine and compressor isentropic efficiencies are each 100%.
(b) the turbine and compressor isentropic efficiencies are 88 and 84%, respectively.
(c) the turbine and compressor isentropic efficiencies are 88 and 84%, respectively, and a regenerator with an effectiveness of 80% is incorporated.
