Flow factor cv
WebA Cv of 350 means a valve will pass 350 gpm of 60oF water with a ∆p of 1 PSI. GENERAL NOTES 1. Liquid flow data is based on pressure drop and flow rate with viscosity similar to water at 60 oF using flow coefficient. 2. Nomograph flow rate for gases is in cubic feet per minute (cfm) at flowing conditions. To convert flow rate from stan- dard ... 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.

WebSummary. Flow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve. Flow coefficient is an imperial measurement and is … WebFlow Calculation for Gases The coefficient of flow (Cv) is a formula which is used to determine a valve’s flows under various conditions and to select the correct valve for a flow application. The Cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º F water with a pressure drop across the valve of 1 psi.
WebThe flow factor, or flow coefficient of a valve shows the relationship between the pressure drop and the flow rate. K v is the flow coefficient in metric units, and can be calculated … 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.
