Consider a compressor in which air enters at 1 bar, 27°C andexits at 3.5 bar, 127°C. The work required is 127 kJ/kg of airflowing through the compressor. Heat transfer between thecompressor and environment occurs at 27°C.
Determine
(a) the heat transfer, in kJ/kg
(b) the entropy generation rate, in kJ/kg.K, for the compressoras a control volume
(c) the entropy generation rate, in kJ/kg.K, for the compressorand the surrounding environment
(d) the entropy generation rate, in kJ/kg.K, for the environmentalone.
