Flow factor cv
WebOrifice Diameter to Flow Coefficient. Calculate the flow coefficient, Kv, cv, or Av, from a given orifice diameter. Note: - You cannot use commas (,) as decimal points. Please use periods (.) Example: 1.02 not 1,02. WebThe use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.

WebJan 28, 2024 · Cv is based on the volume flow rate of water at 60°F through a device within one minute at a 1 psi differential. However, there is a problem with using this equation in pneumatic applications. Because air is compressible, Cv must have additional factors built into the equations to compensate for that compressibility. WebFor that purpose resistance coefficient K, equivalent length L/D and flow coefficient Cv, Kv are used. These values are available from different sources like tables and diagrams from different authors and from valves manufacturers as well. Kinetic energy, which is represented as head due to velocity is generated from static head and increase or ...

Its value can spread from very low …
WebMar 31, 2015 · The flow factor is the metric form and a simple conversion factor shown below can be used. Loss Factor, K: The loss factor is a constant directly proportional to the pressure drop across the component. As the K factor increases so does the resistance to flow. Pressure drop is in units of Psid and the fluid velocity is in units of ft/s. WebThe minimum required Cv value is often listed in a valve’s product description, or wherever its specifications are found. Cv value = Flow coefficient in imperial units. Defined as: …
