Question

A hydraulic ram is a device that uses the pressure created by a large amount of water falling a small distance to raise a portion of that water to a much greater height. It is suitable in valleys where springs feed a stream below, where farms needing irrigation are at the top of the valley. Suppose a spring feeding a hydraulic ram pours water with a speed of 2.00 m/s into a pipe, which descends a certain distance to the base of the ram. At the ram's base, the water has a speed of 7.93 m/s. How far has the water descended? Assuming that the pressure at the two levels is the same.

-This is dealing with bernoulli's equation.
