ABCD, please look what what I replied in your last posts.
Follow the steps to get a numerical answer.
Consider air as an ideal gas with Cp=1000 J/(kg.K), R=287 J/(kg.K) and γ≈1.4. It is compressed from 1 bar, 300K to 10 bar using a compressor. The compressor can be considered adiabatic but not reversible. The flow rate is 2 kg/s, and the entropy production rate is 200 W/K.
1.What is the change in specific entropy of the gas (units of J/(kg.K)) as it moves from inlet to exit?
2.If the process was reversible apart from being adiabatic, what would have been the final Temperature (in kelvin) of the gas at the exit?
3.What is the actual temperature of the gas at the exit (in kelvin)?
4.What is the power consumed by the compressor (in kW)? Do not enter the sign.
5.What is the isentropic efficiency of the compressor? Enter the value as a fraction.
