Flow capacity formula
WebThe flow capacity of a valve (Cv) is a quantitative rating of its ability to pass a fluid flow for a set of given pressure and fluid density conditions, defined as the flow rate of water in gallons per minute through the valve given a … WebAug 28, 2014 · While the flow rate logically can never be higher than the capacity of the bottleneck, it can very well be lower, if the demand is insufficient. Utilization: The utilization tells us, how well a resource is being used. It is calculated as flow rate divided by capacity (e.g. 1/40 / 1/25). The utilization always lies between 0% and 100%.
