The change in head across a small turbine is 10 m, the flow rate of w...
The overall efficiency η0 of turbine = volumetric efficiency (ηv)× hydraulic efficiency (ηn)× mechanical efficiency (ηm)
ηo=ηv×ηh×ηm
Overall efficiency.
Water Power =ρ×Q×g×h
Calculation:
Given, η0=0.8, head h=10m/s and Q=1m3/s

Given:
- Change in head (Δh) = 10 m
- Flow rate of water (Q) = 1 m^3/s
- Efficiency (η) = 80%
To find:
Power developed by the turbine
Formula:
Power (P) = ρ * g * Q * Δh * η
Where,
ρ = density of water (assumed to be 1000 kg/m^3)
g = acceleration due to gravity (assumed to be 9.8 m/s^2)
Calculation:
Substituting the given values into the formula:
P = 1000 * 9.8 * 1 * 10 * 0.8
P = 78400 W
Converting the power from watts to kilowatts:
P = 78400 / 1000
P ≈ 78 kW
Therefore, the power developed by the turbine is approximately 78 kW, which corresponds to option B.
