Hoover dam on the colorado river is the highest dam in the united states at 221m, with a power output of 680 mw. the dam generates electricity by flowing water down to a point 150 m below the stop, at an average flow rate of 650 m3/s.

The power in this flow is

Explanation:

Given that,

Distance = 221 m

Power output = 680 MW

Height =150 m

Average flow rate = 650 m³/s

Suppose we need to calculate the power in this flow in watt

We need to calculate the pressure

Using formula of pressure

Where, = density

h = height

g = acceleration due to gravity

Put the value into the formula

We need to calculate the power

Using formula of power

Put the value into the formula

Hence, The power in this flow is

they should be similar or the same
