HINTS:
-----------
* You can assume that the water is an incompressible liquid.
* You can approximate the specific volume to be saturated liquid at 25 C. (Use this value to calculate the mass flow rate.)
* Remember that the deltaKE is only zero when the diameter at the inlet and exit for a pump is the same, which is not true for this problem!

A1 = 0.0019635 m^2
Ws = -347 hP
