A pump feeds 100,000 lbs/hr of mirbane oil @ a temp. of 68OF (sp.gr. = 1.21, µ=2.15 x 10-3 Pa-s) from a tank @ atmospheric pressure into a reactor where a gauge pressure of 0.1 atm. is maintained. The pipeline is made of steel pipes with a diameter of 89 x 4 mm (o.d. x thickness) having a insignificant corrosion. The equivalent length of the pipeline is 45 m. The pipeline is provided with an orifice (d.o. = 51.3 mm), 2 gate valves (before & after pump, and 4 pipe bends @ an angle of w/a bending radius of 160 mm. The liquid is lifted to a height of 49.32 ft. What is the pressure head (SI units)in the piping system? pressure head loss in the orifice? power (kW) consumed by the pump, assuming that its overall efficiency equals to 0.60.
