Finding mass flow rate

  1. Oct 7, 2012 #1
    1. The problem statement, all variables and given/known data
    A pump steadily delivers water through a hose terminated
    by a nozzle. The exit of the nozzle has a diameter of 0.6 cm
    and is located 10 m above the pump inlet pipe, which has a
    diameter of 1.2 cm. The pressure is equal to 1 bar at both the
    inlet and the exit, and the temperature is constant at 20° C. The
    magnitude of the power input required by the pump is 1.5 kW,
    and the acceleration of gravity is g = 9.81 m/s^2. Determine
    the mass flow rate delivered by the pump, in kg/s.


    2. Relevant equations
    Not sure. I think
    m_dot (deltaPE) = W

    I don't know if I can use the work by the pump though.
    m_dot = rho*Volumetric flow rate

    3. The attempt at a solution
    Well these are the only equations I can think of and I'm not sure if these are right. Any help where to go form here would be appreciated.

    Someone else pitch in! I get an unwieldy third-order polynomial!
