The basic formula for potential energy $($PE$)$ shown on slide $17$ is PE $=$ mgh$.$ The power

output from an impounded water body at a head of $$h$$ above the hydro station can be

determined by following the basic principle $\backslash$rho gQh from the basic formula of potential energy.

$($b$)$ Given an available head of $590$ ft $(182\mathrm{.}3$ m$)$ from the Hoover Dam and a flow rate of $650$ m$3/$s$,$

what is your estimate of the power output $($MW$)?$

$($c$)$ What is your estimate of energy output in terms of MWh per year?

$($d$)$ Compare your results to the recorded$/$actual energy output $($MWh$).$
