- 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_forward6. 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.
