Question

Repeat Problem 9-129, assuming an efficiency of 84 percent for each compressor stage and an efficiency of 88 percent for each turbine stage. A gas turbine has two stages of ideal compression, expansion, intercooling and reheating. Air enters the first compressor at 13 psia and 60degreeF; the total pressure ratio (across all compressors) is 12; the total rate of heat addition is 500Btu/s; and the cold air temperature is increased by 50degreeF in the regenerator. Calculate the power produced by each turbine, power consumed by each compressor, and the rate of heat rejection. Use constant specific heats at room temperature.
