RECTANGULAR TO ROUND TRANSITION CALCULATOR RECIPES

Web Here is a visual representation of the cross-section of rectangular and round ducts: To transform the area (A) of a rectangular duct to the area of round duct (circle A), we have to use this equation: a × b = π × r2 and r = d/2. If we do little math on this equation and express d (equivalent diameter of the round duct), we get rectangular to ...
