Known: water height H (m), inlet flow Q (m^3/s), electricity production P:
P = 9.8HQn (KW)
In the formula n is the efficiency of the hydraulic generator unit = 85% (general hydroelectric power plant turbines are 75% to 85%)
P = 9.8*30 *3*85%=749.7(KW)
You can estimate the following questions yourself
