Question

Water is falling on the blades of a turbine at the rate of 8x102 Kg per minute, the height of the fall is 50m. Calculate the
power given to the turbine. (g = 10 m/s2
)

Answer 1

Answer:

$\huge \color{yellow} \colorbox{red}{answer.}$

Given, Height of fall, h = 50 m

Acceleration due to gravity, g = 10 m/s2

Mass of water, m = 8 × 102 kg Time taken, t = 1 min = 60 s

Therefore, the power given to turbine

$= \frac {energy}{time} = \frac{mgh}{t} = \frac{8 \times {10}^{2} \times 10 \times 50 }{ 60}$

= 6.67 × 103
