In a reciprocating compressor 0.1 m^3 of air at 0.95 bar and 32  C is compressed according to PV n =constant until the pressure is 7 bar. Determine the volume and temperature of the air after compression. The work done on the air and the heat rejected to the cylinder walls assuming the compressor is water cooled and n=1.1

Help with this problem

CO2 needs to be compressed from p1=1bar, t1=300k to p2=40bar to transport it to remote sites for sequestration. what is the minimum energy requirement per kg of CO2 for the compressor? Should the compressor operate adiabatically or isothermally for the best energy efficiency? The environment is at Tenv=300k. Use accurate thermodynamic data for CO2 in this problem.

Hi, Please find attahced two images. I understand there is more than one question here. Please feel free to take more credits to allow answersfor both parts, Thanks
