Homework Help: Cp/Cv ratio experimental error

  1. Nov 9, 2014 #1
    1. The problem statement, all variables and given/known data
    Hello, Everyone!

    So I recently did an experiment in which I pressurised a vessel and then allowed some of the air to move into a smaller vessel and wait for the pressures to stabilise. I then calculated the Cp/Cv ratio and it was slightly lower than the expected 1.40. I am wondering what would cause the value to be lower

    2. Relevant equations

    3. The attempt at a solution

    For a start I think that the equipment was a bit leaky, which would make me think that the pressure would drop so the value of Cp would be smaller, lowering the ratio.

    I'm a bit stuck for any others, can anyone lend a hand?
