In a Brayton power cycle with a compressor isentropic efficiency of 83% and a turbine isentropic efficiency of 88%, there is a pressure drop of 20 kPq between the compressor and the turbine. If the pressure and the temperature at the compressor inlet are 1 bar and 290 K, and the pressure at the compressor outlet is 10 bar, and the temperature before the turbine is 1400 K, determine the cycle efficiency and the entropy generation in the compressor. (all the quantities may be calculated per unit of mass, and air is considered as an ideal gas)

Transcribed Image Text:In a Brayton power cycle with a compressor isentropic efficiency of 83%
and a turbine isentropic efficiency of 88%, there is a pressure drop of 20 kPq between the
compressor and the turbine. If the pressure and the temperature at the compressor inlet are 1 bar
and 290 K, and the pressure at the compressor outlet is 10 bar, and the temperature before the
turbine is 1400 K, determine the cycle efficiency and the entropy generation in the compressor.
