Homework Statement
A pump is required to lift 800 kg of water (about 210 gallons)
per minute from a well 14.0 m deep and eject it with a speed
of 8ms-1 (a) How much work is done per minute in lifting the
water? (b) How much work is done in giving the water the kinetic
energy it has when ejected? (c) What must be the power output of
the pump?
Homework Equations
Work Energy theorem
The Attempt at a Solution
The book attempt was that work done = mgh... Why don't we add tension as well... Or force applied by pump?
