A reservoir has a head of 40 m and a channel leading from the reservoir permits a flow rate of 34 m³/s. If the rotational speed of the rotor is 150 r.p.m., what is the power of the turbine? 

(Take g = 9.81 m/s²)

[A] 14.34 MW
[B] 13.34 MW
[C] 12.34 MW
[D] 11.34 MW

ANSWER= [B] 13.34 MW

The correct answer for A reservoir has a head of 40 m and a channel leading from the reservoir permits a flow rate of 34 m3/s. If the rotational speed of the rotor is 150 r.p.m., what is the power of the turbine?  is 13.34 MW

Detailed Solution for Civil Engineering Exam

Given Data

H = 40 m

Q = 34 m³/s

N = 150 rpm

g = 9.81 m/s²

Power output of turbine = n × ρgQH

Power output of turbine = 1 × 1000 × 9.81 × 34 × 40

Power output of turbine = 13.34 MW
