Regeneration, Reheat, and Compression with
Chapter 9, Problem 66P(choose chapter or problem)
An air-standard Brayton cycle has a compressor pressure ratio of 10. Air enters the compressor at \(p_{1}=14.7 \mathrm{\ lbf} / \mathrm{in}^{2}\), \(T_{1}=70^{\circ} \mathrm{F}\) with a mass flow rate of 90,000 lb/h. The turbine inlet temperature is \(2200^{\circ} \mathrm{R}\). 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.
