Question

Given:

diameter of pipe in point 1 = 3.9in
diameter of pipe in point 2 = 2.5in
specific gravity of the liquid = 0.79
h(ft) = 0.60ft
pressure at point 1 = 14.6 psia
pressure at point 2 = 49 psia
pump and motor efficiency = 66%
diameter of pipe in point 4 = 4.5in
diameter of pipe in point 5 = 2.3 in
Z3 = 35ft

With the schematic diagram of a pump, tanks, and piping determine the following:
1) The velocity of the liquid at point 2 (ft/s)
2) Pump work used by the liquid (Wpump U) (hp)
3) Electric motor power in out (kW)
4) In figure 3, the shaded (pink) in the U tube is mercury; determine y. specific gravity of mercury 13.7
5) Mass flow rate
