Question

a pump is used to lift 100 kg of water from a well 60 m deep, in 20 s. if force of gravity on 1 kg is 10 N,find:(1) work done by the pump(2) potential energy stored in the water(3)power spent by the pump (4)power rating of the pump.state the assumption if any.​

Answer 1

Answer:

work done is equal to MGH

= 100 multiply 10 multiply 60

potential energy stored equals to work done

into 6 into 10j

power is equal to work done equal 6 into 10 by 20

= 2.3 into 10 = 3 into 10 = 3 KW let pump acted on 220 v power ratings equals to 300 volt -200 volt
