Question

water is falling on the blade of a turbine at the rate of 8*10^2 kg per minute, Height of fall is 50 m calculate power given to turbine. (take g=10ms)​

Answer 1

Answer:

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

Answer 2

Answer:

6.5 KW

Explanation:

Power = work /t

power = (mgh)/t

power= (m/t)gh

power= 13.33 x 9.8 x 50

power= 6533.3 W

power= 6.53KW
