![]() Repeat steps 6 to 8 for 5 values of Qactual.Measure and record the actual volume flow rate (Qactual).Measure and record the value of h1 and h2.Adjust the valve on the left side of the Venturi tube to a certain position.Try to remove air bubbles from the apparatus. Connect the manometer hoses to the pressure tapping points of the Venturi tube.Verify the direction of flow in the pipe. ![]() Venturi tube and return back to the tank. Close all valves except those that will let the water flows from the tank to section.Fix the Venturi tube into section 6 as shown in Figure 1.Record the inlet and throat diameters of the Venturi tube.Venturi tube and orifice plate (apparatus measurement) Plate with a sharp square edge hole in the center inserted in a pipe.īernoulli’s equation (with no loss assumption): In a pipe using the pressure drop measurement across the plate. ![]() The orifice plate flow-meter provides a simple and low cost method formeasuring the flow rate Venturi tube is a device in which pressure energy is converted into kinetic energy and it is usedįor measuring the rate of flow of liquid through pipes.
