How Is Force Calculated on Turbine Blades by Water Impact?

[smbascug]

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
