flow coefficient
[/floʊ koʊˈɛfɪʃənt/]
nounpl: flow coefficients
coeficiente de vazão
1. A dimensionless number used in fluid dynamics and hydraulics that represents the relationship between actual flow rate and theoretical flow rate through an opening or restriction
The flow coefficient of the valve was calculated to be 0.65, indicating that the actual flow was 65% of the theoretical maximum.
O coeficiente de vazão da válvula foi calculado em 0,65, indicando que a vazão real era 65% do máximo teórico.
2. A parameter used in engineering to measure the efficiency of flow control devices such as valves, orifices, and nozzles
Engineers selected a pump with a higher flow coefficient to ensure adequate water distribution.
Os engenheiros selecionaram uma bomba com maior coeficiente de vazão para garantir distribuição adequada de água.
This is a technical term primarily used in engineering, hydraulics, and fluid mechanics industries in both Brazil and the USA. In Brazilian engineering contexts, 'coeficiente de vazão' is the standard terminology found in ABNT (Associação Brasileira de Normas Técnicas) standards and technical manuals. The Cv notation is internationally standardized and widely recognized in both countries' industrial sectors. Understanding flow coefficients is essential for professionals in water distribution, HVAC systems, and industrial piping design.
