To calculate the area of a duct reducer, you first need to measure the diameters of the larger and smaller ends of the reducer. Then, calculate the radii of both ends by dividing the diameters by 2. Next, use the formula for the area of a trapezoid (A = (b1 + b2) * h / 2), where b1 and b2 are the radii of the larger and smaller ends, and h is the height of the reducer. Finally, plug in the values to find the area of the duct reducer.
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
Dimension is : W * D* L IN MTR AREA SQ.MTR= (W+D) * 2 * L
Flatten it out then measure it with a ruler! ;)
In order to calculate the area of HVAC duct offset and elbow, one must first measure the distance between the two. Then the elbow must be larger than any cross section to maintain airflow.

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.
A= 2*(w+h)*(l1+l2) W=width H=Height L1, L2 Length of Elbow
To calculate duct area, multiply the width of the duct by the height of the duct. This gives you the area in inches or centimeters, depending on the unit of measure used for the calculation.
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.
