A water pump increases the water pressure from 15 psia to 80 psia.

a. Determine the flow work, in Btu/lbm, required by the pump. Assume that
the state of the water at pump inlet is saturated liquid and that the specific
volume remains constant during this process.

b. Water enters this pump through a 1.5-in-diameter opening and exits
through a 2-in-diameter opening. Determine the velocity of the water at the
inlet and outlet when the mass flow rate through the pump is 1.1 lbm/s
