Calculate the velocity on which the pump will fill

  1. Jul 22, 2013 #1
    1. The problem statement, all variables and given/known data

    A water pump of 1 kilowatt of potency supplies a water-box located 5m above of the water-box where the pump is located. Calculate the velocity on which the pump will fill the water-box.

    NOTE: Sorry for the bad English.

    2. Relevant equations

    potency = work/time

    work= mass x gravity x height

    The rate at which the pump is doing work - 1 kW - tells us the amount of energy that is supplied to the water per second. Part of this energy is used to raise the water's potential energy. The rest of the energy will then become the ......
