Correct Answer - Option 2 : 13.34 MW
Concept:
The power (P) is given by:
P = ρ g Q h
Where ρ is density, g is the acceleration due to gravity,
Q is discharge, and h is the head.
Calculation:
Given that:
Discharge (Q) = 34 m3/s
Density of water (ρ) = 1000 kg/m3
Net head (h) = 40 m
Acceleration due to gravity (g) = 9.8 m/s2
Power of the Turbine (P) = ρ g Q h = 1000 × 9.81 × 34 × 40
= 13341600 W = 13.34 MW
