Transcribed Image Text:Problem 6.149 (8th Edition)
Air at 300 K, 1 bar enters a compressor operating at steady-state and is
compressed adiabatically to 1.5 bar. The power input is 42 kJ per kg of
air flowing. Employing the ideal gas model with k = 1.4 for the air and
ignoring kinetic and potential energy effects, determine, for the
compressor, the rate of entropy production in kJ/K per kg of air
flowing.
