Homework SourseA water tank is shaped like an inverted cone with height 28
A water tank is shaped like an inverted cone with height 28 m and radius 3.5 m.
a. If the tank is full of water, how much work is required to pump the water to the level of the top of the tank and out of the tank?
b. Is it true that it takes half as much work to pump the water out of the tank when it is filled to half its depth as when it is full? Explain
Really need help, been stuck on this forever

Solution
W=?PE=mg(2h/3) The CM of a cone is 2h/3 from its base\'s center. a) W=65.71MJ b) True. Wfull=?PE=mg(2h/3) Whalf=\\(W=?PE=mg(2h/6)
