When Bernoulli’s theorem is applied to an orifice plate flowmeter, the difference in pressure across the orifice plate provides the kinetic energy of the fluid discharged through the orifice. As seen previously, the velocity through the orifice can be calculated by use of Equation 4.2.10:

WebThe basic concept of the orifice plate is a circular plate with a hole in the middle attached to the pipe to measure the flow rate by making pressure down on it. The orifice plate is basically a cylindrical tube in the form of a thin hole in the middle. Thin holes basically force fluid to flow faster through a hole to maintain the flow rate. WebJan 12, 2024 · Abstract. Orifice flowmeters are widely used in industries to measure the flowrate in pipelines. The flowrate inside the pipe can be calculated using the relationship between the flow velocity and the pressure drop across the orifice plate. In the present study, numerical simulations have been carried out using three-dimensional Reynolds …
