Question

2. Suppose you have a conical tank of height 4m and radius 1m filled with a liquid of density p(shown below).

(a) Calculate the work required to pump all of the liquid to the top of the tank. (Your answer will be in terms of p.) (b) Now suppose your tank is inverted.

Calculate the work required to pump all of the liquid to the top of the tank (now thevertex of the cone) in this case.
