- SAMPLE PROBLEMS #3 A venturi meter with a 10.16 cm throat is installed in a 15.24 cm pipe which is inclined upward at an angle of 45 degrees to the horizontal. If the distance between pressure tape along the pipe is 1.5 m, the differential pressure is 70 kPa, and the water temperature is 70°C, what is the discharge of water in m'/sec? Assume coefficient of 0.985.arrow_forwardQuestion 3 A pipe of 150mm bore is delivering water at the rate of 7500 dm/min at a pressure of 820 kN/m?.It connects by a gradually expanding pipe to a main of 300 mm bore which runs 3m above it. Find the pressure in the 300mm main?arrow_forwardPlzz solve all part pleasearrow_forward
- 6. A pump is located 4.5 m to one side of, and 3.5 m above a reservoir. The pump is designed for a flow rate of 6 L s'. For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of the water gage.

If the flow rate through the system is 0.50 m3/s, what is the pressure at point 2? Neglect minor losses. All the pipes are steel with roughness value of 0.046 mm. Also, determine the fraction of the flow in each of the parallel pipes and check your solution.

The first pipe, which goes from A to B has a diameter D=0.12m and is 12 m long. The V %3D second pipe, which goes from B to C has a diameter D2=0.32m and is 13m long. The Darcy-Weisbach friction factor is the same for each pipe and is approximately equal to Hi 2=0.017. The water level Pn into the upstream reservoir is H,=10 m and the volumetric flow rate in the Datum z=0 system is Q=0.02 m³/s. 3.1) Sketch the Hydraulic Grade Line (HGL) and the Energy Grade Line (EGL) considering all losses (abrupt expansion K, = (1- ) %3D Compute the gauge pressure Pn read by the Bourdon manometer right downstream of the sudden expansion (assume the centre of gravity of the manometer is located at z=2.5m). 3.2)arrow_forward
