Question

consider a turbine working under a head of 60m developing a power of 5MW of useful power. The power developed by the turbine when the head is increased to 120m approximately will be​

Answer 1

Answer:

10 w

Explanation:

Thus the power will be 10 MW

Explanation:

We are given that:

Developing power = 5 MW

Height of head = 120 m

Power = mgh / t

Power is directly proportional to height "h"

P1 / P2 = h1 / h2

5 / P2 = 60 / 120

P2 =  120 x 5 / 60

P2 = 2 x 5 = 10 MW

Thus the power will be 10 MW
