The discharge coefficient is a dimensionless number used to characterise the flow and pressure loss behaviour of nozzles and orifices in fluid systems. Orifices and nozzles are typically used …

In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio …

A discharge coefficient c d = 0.975 can be indicated as standard, but the value varies noticeably at low values of the Reynolds number. The pressure recovery is much better for the venturi …

A.2. ORIFICES An orifice is a submerged opening with a closed perimeter through which water flows. Orifices are analyzed using the following equation: Q = CA 2gh where: Q = Discharge in …

discharge coefficient, which is defined as: “In a nozzle or other constriction, the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an iden - …

In simple terms, the discharge coefficient is the ratio of theoretical and actual flow rates. The coefficient of discharge is a dimensionless parameter. It is one of the three hydraulic …

Although the orifice plate isthe recognized flowmeter for the measurement of natural gas and light hydrocarbon liquids, the orifice discharge coefficient equation inuse inthe international …

2015年1月1日 · The discharge coefficient is required to measure flow using a differential-pressure meter. This chapter considers the discharge-coefficient equation for orifice plates: its history, …

The coefficient of discharge for venturi meters ranges from 0.9 to about unity in the turbulent flow range and varies with the diameter ratio of throat to pipe. The coefficient of discharge for …

equation to calculate the flow coefficient for orifice meters. They derived this equation by cross-plotting the data on large graph paper to obtain the best curve fit.
