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...

SECTION A Petroleum distilate is pumped from one large diameter tank to another higher tank, via a pumping station in an oil refinery. The petroleum is pumped at a speed of 2 ms through a 150 m long pipeline of 100 mm internal diameter. The vertical distance pumped is 20 m. The sum of the entry, exit and other component losses is equivalent to 5 times the velocity head, Table Q1 Fluid density Friction factor f for the...

Prior to making a polymer solution for coating plastic film a solvent is pumped into a jacketed carbon steel, Teflon®-lined vessel that is 3 m in diameter with a straight side of 4 m. The liquid depth is 3 m and the jacket extends 3 m up the vessel side. The vessel has an agitator installed. The impeller is a glass-lined hydrofoil that is 1210 mm in diameter with a power number of 0.39 operating at 125 RPM. The fluid...

Q 3 Ninety-eight per cent sulphuric acid is pumped at 4.5 tonne/hour through a 25 mm diameter pipe, 30 m long to a reservoir 12 m higher than the feed point. Calculate the pressure drop in the pipeline. It is given that the viscosity of acid is 25 mN.s/m2 and the density of acid is 1840 kg/m3 and the roughness of the pipe is 0.05mm. Recalculate the pressure drop if the roughness of the pipe is 0.5 mm.

You need to pump water at 20 C from an open reservoir at flow rate of 1.4 x 10^-3 m3/s through a pipe with an inside diameter of 0.03m, using a centrifugal pump having an (NPSH)aq =2.5 m and the equivalent length on the suction side is 3m. There are several minor losses: four standar 90 flanged elbows, and fully open flanged globe valve, fully open flanged gate valve, and the Entrance. What is the the maximum distance above the...

A centrifugal pump test yields the following data: Pump Head Flow (m)(L/min) 30 25 20 40 The pump curve can be approximated by a parabola. This pump draws water from a large reservoir. The discharge of the pump feeds 150 m of 1.5 cm inside diameter pipe and then 225 m of 3 cm inside diameter pipe.. The two pipes both have a roughness of 0.5 mm The 3 cm pipe discharges to atmosphere a distance 40 m below the...

A pumped-storage hydroelectric plant generates high value electricity during peak demand times, by allowing water (density 1,000 kg/m3) to run through a pipe from an elevated reservoir through a bank of turbines and then into a lower level reservoir. It then uses low-cost, off-peak electricity to pump the water back up into the upper reservoir The water surface in the very large upper reservoir (A) is 600 m above datum whilst that in the very large lower reservoir (B) is...
