Question

Hoover Dam on the Colorado River is the highest dam in the United States at 221 m, with an output of 1300 MW. The dam generates electricity with water taken from a depth of 107 m and an average flow rate of 650 m3/s.(a) Calculate the power in this flow in watts. WAns: 7.26e8(b) What is the ratio of this power to the facility's average of 680 MW?

Answer 1

Given:

Height = 211 m

Power output = 1300 MW

Depth of water = 107 m

Average flow rate = 650 m³/s

Let's solve for the following:

• (b). What is the ratio of this power to the facility's average of 680 MW?

To find the ratio, apply the formula:

`r=(P)/(F_P)`

Where:

r is the ratio

P is the power flow = 7.26e8 W = 726 MW

Fp = 680 MW

Thus, we have:

`\begin{gathered} r=(726)/(680) \\ \\ r=1.07 \end{gathered}`

Therefore, the ratio of this power to the facility's average is 1.07

ANSWER:

1.07
