To Define Arc length for Pipe Elbows in OpenPlant Modeler.
In OpenPlant Modeler, requirement is to calculate arc Length for pipe elbows & show it in properties.To do so, let's understand the calculation part first.
It has been observed that Length Property for 90 degree long radius pipe elbow of 100 mm calculation displays as Length = Design Length Center to Outlet End + Design Length Center to Run End.
See image below for default calculation in OpenPlant Modeler.
Length = Design Length Center to Outlet End + Design Length Center to Run End
Where,
Design Length Center to Outlet End= 152.4 mm
Design Length Center to Run = 152.4 mm
Length = 152.4 + 152.4 = 304.8 mm
Actual calculation for Arc Length should be,
Arc Length S = R * θ
where R = 1.5*D = 152.4 mm = Design Length Center to Run End or Design Length Center to Outlet End
This is same as the below formula
where,
Note –In OpenPlant Modeler unit conversion 1” = 25.4mm
hence desired value would be,
The Arc length would be = 239.389 mm
it can be calculated by measure tool as shown
See below steps to overcome this situation by defining a new property in schema through class editor and applying the mathematical expression in EC expression. Also, note that this wiki article is only for Long Radius Elbow. Steps/calculation can vary for any other types of elbows
