Homework Help: Hoover Dam

  1. Apr 4, 2005 #1
    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?
