Thermodynamics flow processes, need help

  1. Mar 20, 2015 #1
    1. The problem statement, all variables and given/known data
    Air at 1 bar and 20°C flows steadily at a rate of 2 m^3/min into a compressor. It leaves at a
    pressure of 15 bar and 120°C. The heat lost from the compressor is 10% of the work transfer to it.
    Find these work and heat transfers, assuming that air behaves as a perfect gas and the velocity at
    the inlet and outlet is small.


    2. Relevant equations


    3. The attempt at a solution
    I don't know where to start with this problem

    You don't know where to start? Can you even write down a relevant equation? What are you covering in your Thermodynamics class right now?
