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.
Input data:
Pressure change: 40Bars
Pipe diameter: 10mm
Fluid density: 30Kg/m3
Mass flow rate: 10Kg / Hr
Click on calculation to output data
K number: 191908
