# Flow Coefficient Calculator

The flow coefficient of the gadget is a relative measure of its efficiency in allowing liquid flow. The flow coefficient (Cv) of water is the volume of water at 60° F that will flow per minute through a valve with a pressure drop of 1 psi across the valve. Here is the flow coefficient calculator to calculate the Cv with ease. Just enter the water flow, specific gravity, and pressure drop in this Cv calculator water, the tool will update you the Cv automatically.

Code to add this calci to your website  #### Formula:

Cv = q (SG / dp)1/2 Where, Cv = Flow Coefficient in Liquids q = Water Flow SG = Specific Gravity dp = Pressure Drop

### Example:

Calculate the flow coefficient in liquids based on the flow of 50 US gal/m, specific gravity of 30 kg/m³ and pressure drop of 20 psi.

#### Solution:

Cv = 50 (30 / 20)1/2
= 61.2372 gals per minute
