To calculate the square meters of a duct you must add the total length of the straight duct work plus the loss of length from the elbows. A standard elbows measurement is 15 feet for each elbow with a 4 inch diameter or 20 feet for an elbow with a 6 inch diameter.

The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
