Oil (density = 910Kg/m3 and viscosity 3.1 x10-3 Pa-s) is pumped from an open tank to a pressurized tank held at 400KPa gauge. The oil is pumped from an inlet at the side of the open tank through a line of commercial steel pipe (inside diameter 0.8m) at a rate of 5x10-3 m3/s. The length of the straight pipe is 150 m, and the pipe contains 4 (90-degree) elbows and two globe valve half open. The level of the liquid...
Problem 3 Pictured to the right is a pipe with a 90 degree bend and an annulus (a solid pipe on the inside). An important consideration in pipe flow is the losses due to friction, D which is called head loss, h, and is measured in meters. Dimesnionlessly, we can say the following: ionlessly, we can say the following: L V2 Di Do Where the pipe dimensions are listed on the diagram, is average flow velocity, p is viscosity, and...

Tulu mela (PLUD 4151) Assignment Single A (ar U ) inaris M Page 2 of 2 3) Figure bellow shows a pump delivering 840 L/min of crude oil (sg = 0.85) from an underground storage drum to the first stage of a processing system. (a) If the total energy loss in the system is 5 N·m/N of oil flowing, calculate the added head by the pump to the system. (b) If the energy loss in the suction pipe is 2...
Water flows from one large reservoir to another via a pipeline which is 0.9 m in diameter, 15km long, and for which f-0.04. The difference in height between the water surface levels in the two reservoirs is 50m. (a) Ignoring the minor losses in the pipeline, calculate the flow rate between the two reservoirs. (b) Assuming that the pipeline entrance and exit are sharp and that the minor losses are as in Table 1, calculate the discharge now. What is...
