Question

Water is falling on the Blades of a turbine at the rate of 6 * 103 kg per minure .

The height of the fall is 10 m . Claculate the power given to the turbine. Take g = 10 m/s2

Answer 1

ur answer will be :-

h = 10m
g = 10m/s 2
m = 6×103 kg per minute

(*) by putting the values in the formula we have :-

p (power) = w (work done)/ t (Time )
p = mgh/ t
= ( 6*10^3/60) × 10 × 10
= 10.3 × 10 × 10
= 1,030 W

HOPE THIS HELPS.......

Answer 2

h = 10m

g = 10m/s 2

m = 6×103 kg per minute

(*) by putting the values in the formula we have :-

p (power) = w (work done)/ t (Time )

p = mgh/ t

p= 6* 10^3 *10*10/60

P= 10^4

P=10000w
