Why Is Venturi Meter Accurate? Because of its position in the flow formula for Venturi meters, if the coefficient drops due to change in tolerance, tap effect or surface irregularities, the indicated flow rate will be higher than it actually is — this is called “over-registration.” If annular chambers are in use, the pressure produced
What Is Coefficient Of Venturi Meter? The discharge coefficient What is coefficient of contraction of Venturi meter? The coefficient of contraction is defined as the ratio between the area of the jet at the vena contracta and the area of the orifice. The typical value may be taken as 0.611 for a sharp orifice (concentric
What Is The Disadvantage Of Orifice Plate? It requires the flow of axial velocity vectors. It causes a pressure drop in the fluid . Its accuracy is affected by the density, pressure and viscosity of the fluid. The range of measurement of viscosity limits of fluids. What are the advantages and disadvantages of orifice plates?
What Is Difference Between Orifice Meter And Venturi Meter? Venturi meter and orifice meter are used for measuring the volumetric flow rate of the fluid that based on the continuity equation and Bernoulli’s equation. … Whereas the orifice meter consists of a thin plate and a bore. The pressure loss in venturi meter is 10%
