Question

Water is falling on the blades of a turbine at the rate of 6 × 10³ kg per minute. The height of the fall is 10 m. Calculate the power given to the turbine. Take g= 10 m/s²​

Answer 1

$\huge\mathfrak\pink{Solution:-}$

⏩ Here,

*m= 6 × 10³ kg,

*t= 1 min= 60 s,

*h= 10 m,

*g= 10 m/s²

We know that,

P= W/t = mgh/t

= 6 × 10³ × 10 × 10/60

= 10⁴ W

= 10 kW. [The required answer]
