Tube shrinkage K value online calculator



App Description

Enter the value and click "Calculate" to display the result \(K=0.8×sin (\frac {θ}{2})×(1-β^2)(θ≤45°)\)

\(K=\frac {1}{2}×(1-β^2)×[sin(\frac {θ}{2})]^{\frac {1}{2}} (45°θ≤180°)\)

  • θ = progressive angle
  • β = dmin / dmax

Usage example

Input data: progressive angle: 90; β: 10

Click on "Calculate", K Value: -45.6610

Note

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.
