In summary, the conversation discusses the power generated by Hoover Dam using water taken from a depth of 150m and an average flow rate of 650 m^3/s. The suggested method for calculating the power is to use Bernouilli's law, which includes the variables of density (p), gravity (g), and height (y), with the addition of an unknown variable represented as big P.

Hoover Dam generates electricity with water taken from a depth of 150m and with an average flow rate of 650 m^3/s.​

Calculate the power in this flow. Note that the velocity and height of the water are not changed appreciably by the generators, and the pressure at the exit point is atmospheric level.

Hint: Power is given by volume flow rate times energy per unit volume.

what have you done up till now ?

i am sure you know how to apply Bernouilli's law

bernoulli's law
is that:
P + 1/2pv^2 + pgy

where little p is the density, g is the gravity, and y is the height? what is the big P?
 

FAQ: Calculating Power Generated at Hoover Dam

How is the power generated at Hoover Dam calculated?

The power generated at Hoover Dam is calculated by multiplying the water flow rate (in cubic feet per second) by the height of the dam (in feet) and then dividing by 11.8. This calculation takes into account the efficiency of the turbines and generators at the dam.

What is the current power generation capacity at Hoover Dam?

As of 2021, the current power generation capacity at Hoover Dam is 2,080 megawatts. This is enough to power about 1.3 million homes.

How does the power generated at Hoover Dam compare to other sources of electricity?

The power generated at Hoover Dam is considered to be a renewable and clean energy source, as it relies on the natural flow of water. In terms of capacity, it is one of the largest hydroelectric power plants in the United States and can generate more electricity than most coal-fired power plants.

What factors can affect the power generated at Hoover Dam?

The amount of water flowing through the dam, the height of the dam, and the efficiency of the turbines and generators can all affect the power generated at Hoover Dam. Additionally, weather patterns and changes in water levels in Lake Mead can also impact the dam's power generation.

How is the power generated at Hoover Dam used?

The power generated at Hoover Dam is used to supply electricity to the states of Arizona, Nevada, and California. It is also used for other purposes such as irrigation, flood control, and recreation. The electricity is distributed through a power grid and can reach other parts of the western United States.
