I am trying calculate the flow area in a butterfly valve and am having some issues trying to quickly grab area measurements. Currently, I open the valve x amount of degrees, then sketch the profile of the angled butterfly plate, fill it, then measure the area of that filled sketch. It works pretty well but it is VERY time consuming. I have also tried to use the shadow analysis tool but it isn't quite accurate enough for what I need.
Is there a better way???
Sincerely,
Brandon
