Homework Help: Thermodynamics calculating Pressure temp and Volume?

  1. May 10, 2012 #1
    1. The problem statement, all variables and given/known data

    Can someone explain how I would calculate T2 and P2 knowing that 1440kJ/kg of heat was added, Specific Heat Capacity is 0.72KJ/KgK and gamma = [itex]\mu1.4[/itex] and mass = 0.00058kg?

    V1 = 0.000005m^3 V2 = V1
    T1 = 753K T2 = ?
    P1 = 25.12 Bar P2 = ?



    2. Relevant equations

    p2=p1*(v1/v2)^1.4

    p1*v1/T1=p2*v2/T2

    3. The attempt at a solution

    Looks like you have a constant volume process. Therefore Work done = 0, Q= ΔT=Cv*ΔT. You know Q, Cv, and T1 so you can find T2.
