Question

Consider a turbine working under a head of 60m developing power of 5mw of useful power. Power when head will be 120m will be

Answer 1

Answer:

FOLLOW ACCORDING TO THE IMAGE

Answer 2

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
