Otto cycle with polytropic compression and expansion (thermodynamics)

  1. Sep 12, 2011 #1
    1. The problem statement, all variables and given/known data
    attached as pdf (problem 1) (part b)


    2. Relevant equations
    w=p2v2-p1v1 / n-1
    w=mR(T2-T1) / 1-n


    3. The attempt at a solution
    I was able to determine the pressure and temperatures at all points, but to find the work i appear to need the volume, I also looked at w=h2-h1 but im not sure how that would work with air.
    I appear to be overlooking something vital which woudl help me move on and would be very greatful if someone could point me towards it.
