Figure 1 – Venturi Meter (H5) The Venturi meter has three main holes. The system consists of a pipe of several meters plumbed in series. Tables and graphs are used to present the precise data collected on flow rate and pressure. The Venturi meter is constructed as shown in Figure 2. The Venturi meter used in this experiment consists of successive converging, uniform and diverging sections equipped with pressure taps at selected locations. 5x10-3 387 12 2. This measuring technique operation and characteristics was used and by comparing pressure drop that will be calculated that related to the velocity of the fluid in the pipe and calculating the pressure of discharge. Six gate valves are used for directing the flow. This occurs due to the Venturi effect which states that when a fluid flows through a narrower area, the fluid’s velocity increases while its static pressure decreases. Inside the pipe pressure difference is created by reducing the cross-sectional area of the flow passage. Connect the bench supply hose to the upstream (left) side of the Venturi meter. In this paper these DP meter Venturi causes less overall pressure loss in a system and thus saves energy: the overall pressure loss is generally between 5 and 20 per cent of the measured differential pressure. !−0. 6mm D2- 20mm 3. 3 CHARACTERISTIC OF VENTURI METER Objectives To measure the discharge and to investigate the characteristic of a Venturi Meter. All units must follow the MKS system. The report includes the purpose, materials used, procedures followed, data collected, and analysis of results. More specifically, this simple venturi meter, constructed from materials available at a local hardware/auto parts store, was characterized by determining the venturi coefficient and the permanent pressure loss. 8 Meter per Square Second No Conversion Required Venturi Head: 24 Millimeter EXPERIMENTS TO BE PERFORMED The test unit will be introduced in the laboratory before the experiment by the relevant assistant. It also provides background on Venturi meters and the principles of Bernoulli's theorem that they rely on to measure flow rate based on pressure differences. Volume 5 10 15 20 2030 Time (t) IQ (2/3) | Q(m/s) 14H R6 0. It sensed true static pressure at the high- and low-pressure points, but it did so with a short inlet section, a modified transition section, a throat with a length equal to half its diameter and Pipe flow measurement is often done with a differential pressure flow meter like the orifice, flow nozzle, and ventruri meter; Venturi Meters are discussed in this article. The principle of venturimeter is that when a fluid flows through the venturimeter, it accelerates in the convergent section and decelerates in the divergent section, resulting in a drop in the static pressure followed by a pressure recovery in the flow direction. This particular relationship means that the pressure decreases when the velocity increases, so Venturi meters are used where velocity increases are desired. Venturi Meter. Nomenclature Patm = Atmospheric Pressure, usually in Pascals : 101325 Pa [Supplied in Lab] Pstatic = Static Pressure, in Pascals Pdyn = Dynamic Pressure, in Pascals SOLTEQ® Flowmeter Measurement Apparatus (Model: FM101) is designed to measure a flow of an incompressible fluid. A schematic of a standard orifice meter can be seen below in Figure 1. In first part, we want to determine the value of Venturi meter coefficient, after arranging the final form of flow rate equation for C,-0. Objectives: To determine the discharge coefficient of orifice meter. The experiment overall contributed to an enhanced comprehension of Bernoulli's principle. NEL was commissioned by Shell Expro to carry out the calibrations and also to carry out an independent parallel computer simulation study. Theoretical Aspects: 3. Theory Venturi meter is a flow measurement device, which is based on the principle of Bernoulli's equation. 2 LEARNING OUTCOME At the end of this experiment, students are able to: To evaluate the frictional resistance to flow along the venturi meter. An experiment was conducted to find the overall meter coefficient C in the venture meter and orifice tube and results show that the flow rate and ∆h are directly proportional to each other and along with this ∆h and the ∆d are also directly proportional to each other. 192 1. 5 OBSERVATIONS 1. If programs are used a sample hand calculation must be presented. A venturi flow meter is one in which the area gradually decreases and remains constant for a certain distance To calculate the flowrate through pipe using venturi meter. 8 Meter per Square Second --> 9. consist of the orifice meter, the nozzle meter, and the Venturi meter. Bernoulli's Theorem remains as its working principle. 90 141 1. This type of a venturi meter is also known as the Herschel type and it consists of a smooth gradual contraction from the main pipe size to the throat section, followed by a smooth, gradual enlargement from the throat section to the Venturi Meter In this experiment, the validity of Bernoulli’s equation will be verified with the use of a tapered duct (venturi system) connected with manometers to measure the pressure head and total head at known points along the flow. Figure 1: Arrangement of Venturi meter apparatus. This experiment gave us a real understanding of how to apply Bernoulli Equations and Continuity Use this calculator to quickly calculate the actual flow rate through the Venturi tube flow meter with only a few inputs. Bernoulli’s equation works for each meter. The top and bottom 5. 5 12. A manometer panel holds the manometer tubes vertically. 2 PRE-LAB QUESTIONS 1. 71 was used to determine the different pressures acting inside the tube. engineer, Clemens Herschel, in 1898. As we will be using the Venturi Meter in order to measure flow, the Bernoulli equation is an important relation that can help getting velocities from fluid pressures and vice versa. Venturimeter Application: The following application of Venturi meter is: The venturi meter is a flow meter that used where high-pressure recovery is required. The apparatus includes a horizontal Venturi tube, a downstream flow-control valve and manometer tubes. 5 1. The experiment analyzed the head loss and discharge coefficients of venturi and orifice meters by measuring pressure drops. Givens: ρ = 10 3 kg/m 3; ρ Hg = 13. 5 2. To calibrate the given Venturi meter. To determine the variation of C d with NRe. Modified Short-Form Venturi Meter Performance. The pressure at the entrance to the meter is gauge and it is undesirable that the pressure should at any point, fall below absolute. Dec 22, 2019 · The throat pass area of the Venturi meter is smaller than the inlet cross sectional area of the Venturi. tko hrmcg pnasae dvzkiv rggjk skrn mpygjg pck vooqt ogmke
