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 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 ...
Learn how to calculate the discharge coefficient for different types of nozzles and orifices in fluid systems. Find typical values, equations and graphs for various Reynolds numbers and area ratios.
The discharge coefficient - c d - varies considerably with changes in area ratio and the Reynolds number. A discharge coefficient c d = 0.60 may be taken as standard, but the value varies noticeably at low values of the Reynolds number.
1 de mar. de 2022 · Discharge Coefficient (Cd) plays a key role in exploring this relation [2]. In the last four decades, enormous investigations have been carried out to find accurate relations for Cd in different hydraulic structures by conducting laboratory experiments and presetting empirical relations or diagrams [ 3 , 4 ].
The discharge coefficient characterises the relationship between flow rate and pressure loss based on the geometry of a nozzle or orifice. You can find typical values in our article on discharge coefficients for nozzles and orifices.
En una boquilla u otra constricción, el coeficiente de descarga (también conocido como coeficiente de descarga o coeficiente de eflujo ) es la relación entre la descarga real y la descarga ideal, [1] es decir, la relación entre el caudal másico en el extremo de descarga de la boquilla a la de una boquilla ideal que expande un fluido de trabajo idéntico desde las mismas condiciones ...
The discharge coefficient C for a flow nozzle is approximately 0.99 for Reynolds numbers greater than 10 6. At lower Reynolds numbers, because of greater energy loss subsequent to the nozzle throat, C values are lower.
