Flow factor cv
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. 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 with the following equation: where . K …

WebApr 3, 2024 · Lnewqban said: In practical terms, the coefficient is expressed only as a number. To expand/generalize, by definition a coefficient is a unitless multiplication factor, like a percentage. For example, a friction coefficient is a percentage/fraction of normal force "converted" to friction. Similarly, a flow coefficient is a fraction of velocity ... WebIn a general sense, the valve flow coefficient, or C v is a number that represents a valve’s ability to pass the flow through it. The bigger the value of Cv, the more will be the flow …
The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: … See more The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ). Q is the flowrate (expressed in cubic metres per hour m … See more • Discharge coefficient See more 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 …
WebFlow coefficient (Cv) is defined as the number of gallons per minute (gpm) at 60°F that will pass through a full open valve with a pressure drop of 1 psi. Simply stated, a control valve which has a Cv of 12 has an effective port area in the full open position such that it passes. 12gpm of water with 1 psi pressure drop. 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.
WebThere are several common ways to express the losses caused by pipe fittings and equipment. Depending on the calculation programs or methods available and engineer may require to convert between one form or another. This article details the equations required to convert between the resistance coefficient and flow coefficient methods (K, Cv and Kv).
