To move water, the pump must overcome. Friction between the water and the pipe. If the pressure required to overcome friction is 5 psi, how much pressure, in psi, must the pump supply to pump water into the tank?

Actually, your question, as well as the one I answered from Adambelva13 about
Water and the net force of diver, should be posted under the "Science" category,
Under Physics. Psychics deal with paranormal events, i.e. ghosts, e.s.p. and
The like. Either that or under the "Education" category under Homework Help.
