Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

The figure below shows a Venturi meter for measuring the water flow rate through a pipe. The cross-sectional area at Stations 1 and 2 is 0.01 m² and 0.006 m², respectively. The pressure difference between Stations 1 and 2 is measured using a U-tube manometer containing a liquid with a specific gravity (SG) of 1.4. The manometer head is h = 0.5 m. What is the volume flow rate Q through the pipe? Neglect viscous effects. The gravitational acceleration g is 9.81 m/s² and the density of water is 1000 kg/m³.

A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe. The discharge pipe is 120-ft long and terminates at a splitter box, elevation 570. Using C=100, plot the pump curve and the corrected pump curve. Plot the pump discharge curves at each wet well elevation and for C=100 and C=140. What is the pump ϐlow at the low and high wet well elevations for newand old pipe?
Problem 3: Water issues from a hole in a large tank, as shown in the attached figure.Assuming frictionless flow, find L.
Water flows inside a solid cylindrical pipe, which narrows as it goes up to a height h (see diagram below). The lower horizontal section has circular cross-sectional diameter d, whereas the upper horizontal section has diameter d/2. Let us denote A to be a point at the lower horizontal section and B to be a point at the upper horizontal section. The flow speed at A and B is uд and u, respectively. The pressure at A and B is PA and PB, respectively. РА UA Oom Ja d d/21 1 UB h (a) Assuming water to be incompressible, show that the flow speed at B is four times the flow speed at A. (b) Use Bernoulli's equation to find the drop in the water pressure from A to B. Express the result in terms of h, uд, the density of water p, and the acceleration of gravity g. (c) Above certain critical height h, vapour bubbles start to appear at the top horizontal section, which hinders water flow through the pipe. Explain why this happens.
