Homework Help: Homework Help Finding FORCE

  1. Apr 3, 2006 #1
    Water strikes the turbine blads of a generator, that its rebounding velocity is reversed in direction undiminished in magnitude. If the flow rate is 60.0kg/s and the water speed is 16.5 m/s, what is the average force on the blades?

    My question is do i need to find something else in order to find the force?

    I really need help i have a test in two days.....

    Looks like an impulse momentum question....

    (mass)*(change in mass's velocity)=(Avg Foce)*(duration of time), Or

    (change in mass's velcotiy)*(mass)/(duration of time)=(Ave Force), Or

    (change in mass's velocity)*(Flow Rate)=(Ave Force) !!!!!!!

    I hope it helps
