## Power Generation MCQ on 5 meter High Head DAM

Find the power generated by a 100% efficient, hydroelectric power station having 5.0 m head and 1.0 m3/s. Assume water density to be 1000 kg/m3:

1. 17 kW
2. 32 kW
3. 42.5 kW
4. 49 kW

Formula Hint:

P = 9.8 * ηQH

where

P = Power (kilowatts)

η = plant efficiency

Q = discharge flow rate ( m3/s )
