1 CALCULATION OF COEFFICIENT OF DISCHARGE OF ORIFICE PLATE AND FLOW NOZZLE A.NAGABHUSHANA RAO, M.PADMANABHAM ABSTRACT An orifice plate is a device used for measuring flow rate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.a nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe.flow nozzle has high coefficient of discharge than orifice plate. The present work is directed towards the to study the flow through an orifice plate and a long radius flow nozzle' obstruction flow meters are commonly in use to measure flow rates in pipes. Both the orifice and nozzle are modeled inside a pipe with an inner diameter of 50 mm and a length of 1m water in the pipe flows with a mean velocity of 1m/s corresponding to Reynolds number 50,000.Thedischarge coefficients are determined and compared with experimental values.the cut plots,xy-plots,flow trajectories for orifice plate and flow nozzle are displayed. The centerline velocity varies along the length of the pipe for both the cases and plotted pressure, velocity fields. INTRODUCTION INTRODUCTION TO ORIFICE PLATE : An orifice plate is a device used for measuring flow rate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa. DESCRIPTION : Figure : Orifice plate An orifice plate is a thin plate with a hole in the middle. It is usually placed in a pipe in which fluid flows. When the fluid reaches the orifice plate, the fluid is forced to converge to go through the small hole; the point of maximum convergence actually occurs shortly downstream of the physical orifice, at the so-called vena contracta point (see drawing to the right). As it does so, the velocity and the pressure changes. Beyond the vena contracta, the fluid expands and the velocity and pressure change once again. By measuring the difference in fluid pressure between the normal pipe section and at the vena contracta, the volumetric and mass flow rates can be obtained from Bernoulli's equation.
