App Description

Enter the value and click "Calculate" to display the result

\(K= \frac {1.59923 \times P \times d^4 \times P}{W^2} \)

P = pressure change

d = pipe diameter

ρ = fluid density

W = mass flow rate

In some cases, it may be necessary to insert a resistor in the pipe to limit the flow to a given pressure drop to a certain value. The differential pressure calculator calculates the K value required to reach a specified flow differential.

Usage example

Input data:

Pressure change: 40Bars

Pipe diameter: 10mm

Fluid density: 30Kg/m³

Mass flow rate: 10Kg / Hr
