An electric pump needs to be installed on a deep well to provide water. If the well is 30m deep and 50L of water must be pumped out per minute. How powerful a pump is needed ? (watts)

  • physics - ,

    50 l/min = 5/6 kg/s

    Power required = (mass flow rate)*g*H
    = (5/6)(9.8)(30) kg/s*m/s^2*m or W
    = 245 W
