CV Flow Calculator

Formula

To calculate the CV Flow Coefficient (\(Cv\)):

\[ Cv = Q \times \sqrt{\frac{SG}{P}} \]

Where:

\(Cv\) is the coefficient of flow
\(Q\) is the flow rate
\(SG\) is the specific gravity of the fluid inflow
\(P\) is the pressure drop across the valve the fluid is moving through

What is CV Flow?

A CV flow, more commonly known as the coefficient of flow, is a measure of the ability of a fluid to flow through a valve at a certain pressure drop. It helps in determining the flow capacity of a valve and is crucial in various engineering and fluid dynamics applications.

Example Calculation 1

Let's assume the following values:

Flow Rate (\(Q\)) = 100
Specific Gravity (\(SG\)) = 0.8
Pressure Drop (\(P\)) = 2

Using the formula:

\[ Cv = 100 \times \sqrt{\frac{0.8}{2}} = 100 \times \sqrt{0.4} \approx 63.25 \]

The CV Flow Coefficient is approximately 63.25.

Example Calculation 2

Let's assume the following values:

Flow Rate (\(Q\)) = 150
Specific Gravity (\(SG\)) = 1.2
Pressure Drop (\(P\)) = 3

Using the formula:

\[ Cv = 150 \times \sqrt{\frac{1.2}{3}} = 150 \times \sqrt{0.4} \approx 94.87 \]

The CV Flow Coefficient is approximately 94.87.
