Water falls down a `500.0` m shaft to reach a turbine which generates electricity. How much water must fall per second in order to generate `1.00 xx10^(9)` Watts of power? (Assume `50%` efficiency of conversion and `g=10m//s^(2)`)

If the water falls from a dam into a turbine wheel 19.6 m below, then the velocity of water at the turbine is (g=9.8m//s^(2))

Water falling from a 50 m high fall is to be used for generating electric enegy. If 1.8xx10^5kg of water falls per hour and half the gravitational potential energyh can be converted into electric energy, how many 100 W lamps can be it?

How much water per minute a pump of power 2 kW can reise to a height of 10 m ? (g=10 m//s^(2))
