A pump can raise 100 L of water per minute to a height of 10 m . What should be the power of the pump ?

Text Solution

Verified by Experts

Mass of 100L of water ,m=`100xx10^3 g=100kg`
Potential energy by the water per mitute,
V`=mgh =100xx9.8xx10=9800J`
`therefore` Power of the pump =`(9800)/(60) =163.3 J*s^(-1) =163.3W`.
