Question

Q2. Calculate the Power of a pump which lifts 100 kg of water to a water tank
placed at a height of 20 m in 10s. (g=10m/s2)
(2)​

Answer 1

Explanation:

mass of pump =100kg

height =20m

time =10sec

gravity pull or acceleration =10m/s^2

we know that energy =m×g×h

power =energy /time

power =100×10×20/10

power = 2000joule

power =2000/1000 kWh

power = 2kWh
