    Question Duct Fitting Area

    Hey fellas I have found a way to calculate weight from the area of the duct but when it comes to duct fittings I'm not sure of the actual way of getting area into a fitting and to follow the parameters based on size and extensions etc, any suggestions?

    Weight really depends on quite a few things like fitting type, material gauge (determined by pressure class/size), insulation thickness, connectors, seams, etc. You have to imagine each side as a flat part, you'll need to use pi() quite a bit for radius fittings. So focus on get the surface area of each side, then total it.

    Fabrication Parts calculate all weights automatically once you set up the database correctly, it's awesome.

    Yes, Pythagoras is your friend..
    You could simplify the calculation by just calculating the Length of the fitting centreline(s) (Using angle and centre radius, for example). Then calculate the duct area as if it was a straight duct. This will give more area on the inside of a bend and less on the outside, so will be approximately right. Otherwise you will have to set up formulas for each face and add up the areas (lots of partial pizza slices and sections of cylinders...)
    With flanges, strengthening/welding, internal vanes, hangers, etc. it wont be possible to calculate the weight 100% accurately so a simpler calculation might be enough for your needs.

    When we select strait duct its properties showing its area
    why not showing like that for duct fittings.
    What we need to do to show area in duct fittings properties
