Question
A pump is required to lift 800 kg of water per minute from a well 13.8 m deep and eject it with a speed of 17.9 m/s. How much work is done per minute in lifting the water? How much work is done in giving the water the kinetic energy it has when ejected?
Expert Solution
Step 1: Introduction of the given value.
Here
the mass of water lifted per minute = 800 kg
depth of well = h = 13.8m
the ejected speed of the water = v = 17.9 m/s
I have to find
a. The work is done per minute in lifting the water.
b. The work is done in giving the water the kinetic energy it has when ejected.
