Q1:

A hydro-electric reservoir can supply water continuously at a rate of 100 m3/s. The head is 75 m. The theoretical power that can be developed is

A 10000 mhp

B 100000 mhp

C 7500 mhp

D 7500 kW

ANS:B - 100000 mhp

Theoretical power = 75000000 Watt (as calculated above).
1 HP = 746 W.
Theoretical power = 75000000/746 = 100536 HP.
