Figure 8.12 shows a portion of a fire protection system in which a pump draws water at 60°F from a reservoir and delivers it to a point B at the flow rate of 1500 gal/min.
Figure 8.18 shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft/s. The dynamic viscosity of the fluid is 4.0 x 105 lbs/ft². The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.
A centrifugal pump takes brine from the bottom of a supply tank and delivers it into the bottom of another tank. The brine level in the discharge tank is 150 ft above that in the supply tank. The line between the tanks is 600 ft of 4-in. Schedule 40 commercial steel pipe. The flow rate is 400 gal/min. In the line are two gate valves, four standard tees, and four ells. The specific gravity of brine is 1.18, the viscosity of brine is 1.2 cP, and the energy cost is $400 per horsepower-year on a basis of 300 days per year. The overall efficiency of pump and motor is 60 %.
