Carbon dioxide (co2) at 1 bar, 300 k enters a compressor operating at steady state and is compressed adiabatically to an exit state of 10 bar, 580 k. the co2 is modeled as an ideal gas, and kinetic and potential energy effects are negligible. for the compressor, determine: (a) the work input, in kj per kg of co2 flowing, (b) the rate of entropy production, in kj/k per kg of co2 flowing, and (c) the percent isentropic compressor efficiency.
