Air flows through a Venturi channel of rectangular cross section as shown. The constant width of the channel is 0.06 m and the height at the exit is 0.04 m. Compressibility and viscous effects are negligible. (a) Determine the flowrate when water is drawn up 0.10 m in a small tubeattached to the static pressure tap at the throat where the channel height is 0.02 m. (b) Determine the channel height, h2, at section (2) where, for the same flowrate as in part (a), the water is drawn up 0.05 m. (c) Determine the pressure needed at section (1) to produce this flow.
A pipe, 12 inch in diameter at A, discharges 4.0 cfs of heavy fuel oil (sp gr = 0.899) into the air at B, where the diameter is 6 inch. If B is 12 ft above A and the frictional loss between the two points is equivalent to 3.0 lb per sq in, determine the pressure at A in pounds per square inch.
If a dust-proofing oil at 30°C had been flowing at 0.046 m /s through a 150-mm pipe in which along-radius flow nozzle 75 mm in diameter, what would have been the deflection of the mercury? Assume C=0.98.
9.41. A horizontal rough pipe of 150 mm diameter carries water at 20°C. It is observed thatthe fall of pressure along this pipe is 184 kPa per 100 m when the flowrate is 60 1/s. What sizeof smooth pipe would produce the same pressure drop for the same flowrate?
A 50 mm diameter siphon discharges oil (SG=0.88) from a reservoir (elev. 20m) into open air (elev. 15m). The head loss from the reservoir (point 1) to the summit (point 2, elev. 22m) is 2.5 times the velocity head in the siphon and head loss from the summit to the discharge end is 4 times the velocity head in the siphon. What is the absolutepressure at the summit (point 2) assuming the atmospheric pressure to be 101.3 kPa? Do not write the unit. You will only input the numerical answer in the space provided. Unit of the Correct Answer: kPa (indicate the sign if negative) Decimal Places required in the final answer: 3

A venturi meter is introduced in a 300 mm diameter horizontal pipeline carrying a liquid under a pressure of 150 kPa. The throat diameter of the me- ter is 100 mm and the pressure at the throat is 400 mm of mercury below atmosphere. If 3% of the differential pressure is lost between inlet and the throat, determine the flow rate of the pipeline. PLEASE USE BERNOULLI'S ENERGY EQUATION. INCLUDE COMPLETE SOLUTION
HW Question : The tank-pipe system is to deliver at least 12.5 m3/h of water at 20°C to the reservoir. What is the maximum roughness height ε allowable for the pipe? Neglect minor losses.
The following system is fed by a centrifugal pump. The piping is constructed from smooth plastic of OD 55 mm, wall thickness 2.5 mm. The minor losses for the system prior to the pump are given by KL = 12.0. The system curves for this pump are attached. If the flowrate is reduced to 1.4 m3/hr, and the upstream head requirement were 17 m, what would the electrical power requirement of the pump be?
Water flows from a pressurized tank (at 150 kPa gauge) to an open tank 15m above. What is the pressure head developed by the flow?
Water (@ 75°C) flows at a horizontal pipe at a rate of 1.6 m3/min in a pipe. Flow enters a 3 inch 45 deg. elbow and diverted upwards into a connecting pipe. The diameter of the outlet is 2 inches. If the pressure just before the elbow is 78kPa, what is the magnitude and direction of the force to keep the elbow in place? Assume: that frictional losses in the elbow are negligible.
Water flows upwards in a vertical pipeline of gradually varying section from point 1 to point 2, which is 1.5m above point 1, at the rate of 0.9m^3/s. At section 1 the pipe diameter is 0.5m and pressure is 800 kPa. If pressure at section 2 is 600 kPa, determine the pipe diameter at that location. Neglect losses. Show complete solution no shortcut
