(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A small dam produces electrical power. The water falls a distance of 27m to turn a turbine. If the efficiency to produce electrical energy is 65%, at what rate must water flow over the dam to produce 780 kW of electrical energy?

2. Relevant equations

v^{2}= u^{2}+ 2as

P = [tex]\tau[/tex] x [tex]\omega[/tex]

3. The attempt at a solution

I've basically been at this one on and off for a few hours, and have tied myself so completely in knots that I have no idea what I'm doing anymore. Please help someone!
