Homework Help: Heat pumps

  1. Nov 23, 2011 #1
    1. The problem statement, all variables and given/known data
    I am trying to work out the Cop of a heat pump in an experiment, I recorded the temperatures before and after the Condenser, but am unsure of how to calculate the work input to the condenser

    2. Relevant equations
    cop= heat gained at the condenser/ work input to the condenser

    3. The attempt at a solution

    For example at a mass flow rate of 5 m/s , the gain in temperature was 31.5 degrees,
    THE electricity meter read 152.15 kwh and it took 54.64 seconds for a revolution , can anyone help me im totally lost
