    P = WQHη KW
    = 9.81 × 12 × 80 × 0.8
    = 7534.08 KW = 7.53 MW

    The formula for power developed in a hydroelectric plant is:

    P = Qρghη

    where:
    P = power developed (in watts)
    Q = discharge (in cubic meters per second)
    ρ = specific weight of water (in newtons per cubic meter)
    g = acceleration due to gravity (9.81 m/s^2)
    h = available head (in meters)
    η = overall efficiency of the PowerStation (as a decimal)

    Plugging in the given values, we get:

    P = (12)(9.81)(80)(0.80)
    P = 75,878.4 watts

    Therefore, the power developed is approximately 75,878.4 watts.
