A teenager is stealing gasoline from his father's car with a siphon with diameter of 10 mm. The heights in the figure are: z1 = 853 mm and 22 = 92 mm Calculate the volumetric flow rate out of the tank. Round off the answer to two decimal digits in l/s, but enter your answer without the unit. Z₁ 22
A venturi meter is used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe (the figure); the cross-sectional area A of the entrance and exit of the meter matches the pipe's cross-sectional area. Between the entrance and exit, the fluid flows from the pipe with speed V and then through a narrow ''throat'' of cross-sectional area a with speed v. A manometer connects the wider portion of the meter to the narrower portion. The change in the fluid's speed is accompanied by a change Δp in the fluid's pressure, which causes a height difference h of the liquid in the two arms of the manometer. (Here Δp means pressure in the throat minus pressure in the pipe.) Let A equal 5·a. Suppose the pressure p1 at A is 2.1 atm. Compute the values of (a) the speed V at A and (b) the speed v at a that make the pressure p2 at a equal to zero. (c) Compute the corresponding volume flow rate if the diameter at A is 4.0 cm.The phenomenon that occurs at a when…

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.
A water discharge 8 m^3/s is to flow through this horizontal pipe, which is 1 m in diameter. If the head loss is given as 7 V^2/2g (V is velocity in the pipe), how much power will have to be supplied to the flow by the pump to produce this discharge? Plot also the EGL and HGL against the given diagram.
Water flows steadily into the Venturi tube in the following figure. In the section considered, negligible friction losses and uniform properties in the sections are assumed. The entrance area (A1) is 20 cm2, while the throat area is A2 = 10 cm2. A pressure gauge whose manometric fluid is mercury (Yhg = 136,000 N / m3) is connected between the inlet sections and the throat, as seen in the figure. The flow of water that flows through the Venturi tube is requested (γH2O = 10,000 N / m3. Answer .: ϕ = 5.8 L / s.

The task is to to transfer the fluid from the source towards the tank (TANK A) lying on an elevated platform as shown. The goal is to fill up that 16.49 m by 2.23 m by 6.36 m tank (TANK A) within 11.5 mins (from empty to full). Your budget is limited to 605,000 pesos. Head loss on pipe due to friction is 1.23 meters per 1 meter of pipe. Because it's Fluid Machinery and not Engineering Economics, it's ok for your design to exceed the budget BUT YOU HAVE TO JUSTIFY IT.
