Answer:

Given:
efficiency of the turbine,
= 65% = 0.65
available gross head,
= 45 m
head loss,
= 5 m
Discharge, Q =

Solution:
The nozzle is 100% (say)
Available power at the inlet of the turbine,
is given by:
(1)
where
= density of water = 997

acceleration due to gravity, g =

Using eqn (1):

Also, efficency,
is given by:
