Question

a pump is required to lift 1000 kg of water per minute from a well 2m deep and eject it with a speed of 20m/sec
a. how much work is done per minute in lifting the water.
b. how much in giving the water the kinetic energy it has ejected?
c. what must be the power output of the pump?

Answer 1

W=mgh + mv^2/2

m/t=1000

m = 1000*3600

KE = mv^2/2

P=W/t

This is the concept u have to use...
