Flow Coefficient, Cv, to Flow Factor, Kv, Converter

ΔP is the pressure drop across the valve (expressed in psi). In more practical terms, the flow coefficient Cv is the volume (in US gallons) of water at 60 °F (16 °C) that will flow per minute through a valve with a pressure drop of 1 psi (6.9 kPa) across the valve. The use of the flow coefficient offers a standard … See more The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow.

Flow Coefficients and Loss Factors: Valve Transients - AFT Blog

WebThe Kvs value is a special case of the Kv value, which indicates the flow at a given valve position and a pressure differential of 1 bar. The flow at a lower pressure loss can be calculated by rearranging the equation: Kvs = Q / √ΔP where Kvs: Kvs value [m³/h] Q: Flow [m³/h] ΔP: Pressure differential across a regulating valve [bar] WebOct 21, 2014 · The most common 15-kV voltage is 12.47 kV, which has a line-to-ground voltage of 7.2 kV. The dividing line between distribution and subtransmission is often gray. Some lines act as both subtransmission and distribution circuits. A 34.5-kV circuit may feed a few 12.5-kV distribution substations, but it may also serve some load directly. WebThe flow rate value can be determined using a formula; the larger the value, the higher the flow rate will be through the valve at a given pressure drop. Flow rate is expressed as Cv or Kv, depending on the system of measurement being used (imperial or metric, respectively). The minimum required Cv value is often listed in a valve’s product ... optiver mental maths

KV - Wikipedia

WebKv is the flow of water expressed in m3/hr., at 15 Deg C passing at a pressure difference of 1 bar. The flow factor Kv is the most critical parameter. It characterizes the flow through a valve. Sometimes, we use Kv coefficient in place of Cv. There is a certain relationship between Cv and Kv. WebDec 19, 2024 · Kv = 0.865 · Cv. Kv is the flow coefficient in metric units. It is defined as the flow rate in cubic meters per hour [m3/h] of water at a temperature of 16 degrees Celsius with a pressure drop across the valve of 1 bar. Cv = 1,156 · Kv. Cv is the flow coefficient in imperial units. It is defined as the flow rate in US Gallons per minute [gpm ...
