Calculating value of R from P, V, T data and work done in compression process

  1. Mar 27, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate a value of R, specific gas constant for air, from the values you have.

    Also calculate the work done in the compression process.


    2. Relevant equations

    Pv = RT

    ρair = 1.2 kg/m^3


    3. The attempt at a solution

    Have P,V and T data from an adiabatic compression. I think I need initial values for these but not sure what else.

    Also we have been given the density for air so the mass of the air in the tube, m = ρ*V = 2.903172 x 10^-4 kg. However this will change surely as volume decreases?
