## If discharge is 1 m³/s and head of water is 1 m. Assuming 100% efficiency of alternator and

If discharge is 1 m³/s and head of water is 1 m. Assuming 100% efficiency of alternator and turbine the power generated by alternator in 1 hour will be:

1. 825/95 kW
2. 992/88 kW
3. 736/75 kW
4. 1082/92 kW

Explanation: Power generated = 9.8 QHη = 9.8*1*1*1 = 9.8 kW = 736/75 kW
