θ = Progressive angle β = d_minor / d_major

The change in the diameter of the pressure caused by the change in the diameter of the fluid is obtained by fitting. The pressure drop also depends on the speed and changes in the direction of the fit.

This formula is used to calculate the K value of the tube amplification.

Usage example

Input data:

Progressive angle: 90

β:45

Click "Calculate" to output data

K value: 4.09658e+6

Note

Increasing angle input angle less than 180 degrees
