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.

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.
Area of round duct is pi times radius squared.
if the area given is 100 square inches you can use 10" by 10" duct due to a black art known as aerodynamics or compressible fluid flow, you will get the same back pressure in a 10" diameter round duct and a 2" x 50" duct considerably more back pressure a nice manufactured 90 will take as much back pressure as 50' of duct a tight curved 90 will take as much as 100 feet of duct fans have a curve that goes from maximum cfm at no pressure to minimum cfm at max pressure the fan will require the most power when cfm * pressure is highest simple as rocket science i guess
Hopefully I'm understanding this question correctly. I assume you mean a heating or air duct where, if round, is like a cylinder. The volume of a cylinder is equal to (pi)r2h, where pi = 3.142; r = radius; h = height. To understand why this is, picture a round duct or any cylinder. The base is a circle. The area of a circle is equal to (pi)r2. If you stand a bunch of circles on top of each other (equal to the height) the object now looks like a cylinder and the area of all those circles will equal the volume of the cylinder. To answer your question, you calculate the volume of a round duct by figuring out the radius of the base circle and the height of the object and then use the formula (pi)r2h. The answer that you get will be in cubic units.
To calculate the area of an HVAC duct reducer, you measure using a trapezoid area formula, which would be 1/2 times the base plus the top, times the height.
Area of Duct = (Weidth+Height) X 2 X (Length1+Length2)

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.
Dimension is : W * D* L IN MTR AREA SQ.MTR= (W+D) * 2 * L

The Ampulla of Vater..This is the duodenum where the common bile duct and the pancreatic duct empty.
Flatten it out then measure it with a ruler! ;)
A= 2*(w+h)*(l1+l2) W=width H=Height L1, L2 Length of Elbow
In order to calculate square meters multiply the length by the width. In this case 150 meters times 80 meters would yield 12,000 square meters. This is considered the area.
