How to find discharge coefficient (Cd) using orifice diameter and flow …

The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: Witryna28 wrz 2010 · The orifice flow calculation proceeds as follows: Initially and whenever the setting (i.e., the fraction opened) changes, flow coefficients for both orifice and weir behavior are computed as follows: For side orifices, define Hcrit = h/2 where h is the opening height. For bottom orifices:

As expected, the discharge coefficient for the venturi was around 1.0 and 0.6 for the orifice. Figure 7 Reynold’s Number Vs Discharge Coefficient Figure 5 shows the comparison between the Reynold’s number and the discharge coefficient.

WitrynaIn 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 of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same … WitrynaDiscussion The practical was successfully completed by analysing the flow measurement with the comparison of pressure drop by using the flow measuring techniques which are namely the Rotameter, Venturi, and Orifice meter. The flow rates from the Rotameter were used as the parameter to gain flow rates for the Venturi meter and the Orifice …
