A compressor is used to compress air from 1 bar and 290 K to 10 bar. The compression can be assumed to be adiabatic, and the compressed air is found to have an outlet temperature of 575 K. 1.What is the value of delta S for this process? 2. How much work, Ws, is needed per mole of air for the compression? 3. How do you account for excess temperature?
