2. (10 pts) Problem 4.6: The compressor discussed in Illustrations 3.4-4 and 4.51 (gas flow is 2.5mol/s; system is at constant volume; and process is reversible) is being used to compress air from 1bar and 290K to 10bar. The compression can be assumed to be adiabatic, and the compressed air is found to have an outlet temperature of 575K. Hint: assume that the compressor is at steady state. In your calculations you may assume air is an ideal gas with Cp=29.3J/(molK). a) What is the value of S for this process? b) How much work, W,, is needed per mole of air for the compression? c) The temperature of the air leaving the compressor here is higher than in Illustration 4.5- 1. How do you account for this
