Energy released by condensing steam back to liquid water

  1. Oct 10, 2014 #1
    1. The problem statement, all variables and given/known data
    vaporized 19 kg of water and did not capture and condense it. It took 42.9 MJ to vaporize the water, how much energy did I lose from not condensing the steam?

    2. Relevant equations
    Latent Heat of Water = 2260kJ/kg

    3. The attempt at a solution
    Would the energy lost to not capturing the condensation be the equivalent to the energy needed to vaporize the water?

    If your initial water was completely pure, directly at the boiling point and your process was 100% efficient, probably. I doubt that for realistic setups, especially the last part. Anyway, you don't have to care about that to find the answer.
