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.
surface area divided by volume
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.

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.

Lol at your life
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
A= 2*(w+h)*(l1+l2) W=width H=Height L1, L2 Length of Elbow

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.
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
To calculate the pressure exerted on a surface, the force acting on the surface is divided by the surface area. Mathematically, pressure = force / area.
surface area divided by volume
To calculate the pressure exerted on a surface, the force normal to the surface is divided by the surface area. The formula for pressure is pressure = force / area.
