    1. The problem statement, all variables and given/known data
    hiii...i need some help over here.. having a bit of problem with

    A pump is pumping at 1000gm/sec.water level difference between mouth and upper surface of water reservoir is 20 cm. Cross-sectional area of pipe and pump=10 cm^2. resistance of pipe=pump circuit= 2dyne.sec.cm^-5 . What is the power of the pump?

    a) 52.2 watt b)0.2 watt c)2.5 watt d)2.7 watt

    2. Relevant equations

    3. The attempt at a solution
    vol of water flowing out per sec is 100cc
    area = 10cm^2
    velocity = 100cm/sec

    Power = force x velocity
    here, power = resistance x velocity
