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.

How to find the area of round duct?
Area of round duct is pi times radius squared.
How to calculate duct area?
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.
How you calculate the area of HVAC duct offset and elbow in square feet?
200+200
How do you find area of rectangular duct?
Assuming the duct you have in mind is in a 3d shape (length, width, and depth) Your answer will be in a cubic form. Example: Say it is 2 feet long 1 foot wide and 1 foot tall, the area will be 2 cubic feet. Measurement of side one * side 2 * side 3 = area.
How do you calculate duct size with area given?
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

How do you calculate square feet of a round duct?
Flatten it out then measure it with a ruler! ;)
How can measure the velocity in the duct?
existing duct = velometer (Google velometer). Calculate velocity if volume is known and the size of duct volume (cubic feet) multiplied, square feet feet of duct, IE. 1000 cubic foot of air * 12" x12" square duct = 1000 cubic feet * 1sq. foot = 1000 feet per minute
How do you calculate the area of duct reducer?
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.
How do you calculate the area of a duct elbow?
Area of Duct = (Weidth+Height) X 2 X (Length1+Length2)
How you calculate the area of HVAC duct offset and elbow in square feet?

How do you calculate the area of HVAC duct offset and 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.

How do you calculate surface area of a duct?
Dimension is : W * D* L IN MTR AREA SQ.MTR= (W+D) * 2 * L
What is the cross sectional area of a 10 inch metal round duct?
Cross-sectional area = pi*radius2
What is formula for converting face velocity into cubic feet per minute?
You need to know the area of the pipe or duct. If you have that area, in square feet, V = Q/A where V = velocity (ft/minute in this case), Q = flowrate (cubic feet/minute in ths case), and A = area (square feet in this case). Then, you just have to apply conversions to get whatever units you want to present or use the answer in.
