Valve Cv Unit Conversion. Kv = 0.864 m3/ hr. This article demonstrates how to convert between these two parameters when performing functions such as selecting a valve with an equivalent pressure drop to a given orifice plate.
The valve flow coefficient, cv, is the number of u.s. Kv = 0.865 · cv cv = 1,156 · kv (equivalence between flow coefficients kv and cv) It allows you to calculate the flow or c v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate.
Kv = 0.864 m3/ hr.
Flow coefficient is an imperial measurement and is defined as: ※2 calculation of viscosity correction is necessary when the fluid is liquid and the kinematic viscosity is 20 mpa・s or more and the calculated cv value is 0.01 or less. Equations displayed for easy reference. The pressure drop or flow rate through a valve or orifice plate is typically calculated using the a flow coefficient, cv or orifice diameter.
