1. The problem statement, all variables and given/known data

Air flowing at 1 meter cubed / second enters an adiabatic compresses at 20 degrees celsius and 1 bar. It exits at 200 degrees Celsius. The isentropic efficiency is 80%. Calculate the exit pressure and power required.

2. Relevant equations



3. The attempt at a solution

I have no idea how to start, I feel completely lost can anyone offer some insight to get me started at least? Thank you.
