Heavy fuel oil flows at Q = 10 gallons per minute (gpm) in a horizontal steel pipe that connects two storage tanks. The diameter of the pipe is D = 1.5 inches. The length of the pipe is L = 100 feet. The depth of oil in the supply tank is 30 feet above the pipe entrance. The temperature of the oil is 60°F, the specific gravity of the oil is s.g.oin = 0.90, the specific weight of the oil is 56.13 lb/ft', and the kinematic viscosity of the oil is 0.00175 ft2/s. The pipe discharges into the bottom of the receiving tank. Neglect minor losses. a) Determine the pressure p at the pipe entrance in pounds per square foot (psf). b) Determine the velocity v in feet per second (fps). c) Determine the Reynolds number Re. d) Classify the flow based on the Reynolds number Re. e) Determine the Darcy-Weisbach friction factor f. f) Determine the friction head loss hfac in feet in the pipe between the two storage tanks. 8) Determine the depth of oil in feet above the exit from the pipe into the second…
