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

Correct answer: 3. 736/75 kW

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