CBSE Class 12-science Answered
Dear Sir
This question is not exactly from this chapter but from the previous year.
What is the power required to raise 300 litres of water per minute through a height of 6m using a pipe of diameter 2.5m ?(g=10m/s^2)

Expert Answer
Given:
Volume of 300 litres of water, V = 0.3 m³
Density of water, ρ = 10³ kg /m³
t = 1 min = 60 sec
g = 10 m/s²
mass = volume × density
m = 0.3 × 10³ = 300 kg
Power required in pulling up this water to height of 6 m is given as,
Hence, 300 W power required to raise 300 litres of water per minute.
