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.
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

The cross-sectional area of a 10-inch round metal duct can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius of the duct. For a 10-inch round duct, the radius would be half of the diameter (10 inches), so the radius is 5 inches. Plugging in this value into the formula gives A = π*5^2 = 25π square inches, or approximately 78.5 square inches.
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.
"no bile duct dilation" means the diameter if the bile duct is normal.
To calculate the duct diameter, you need to consider the airflow requirements, velocity of air in the duct, and the friction losses. Use the Duct Sizing Chart or an online calculator to determine the appropriate duct diameter for your system based on these factors. It's important to ensure that the chosen diameter can handle the required airflow without causing excessive pressure drop.
A2. Assuming you refer to the diameter of air handling ducts, then the cross - sectional area will increase as the square of the diameter. A 10" duct will have an area of pi x (10^2)/4. A 6" duct will have an area of pi x (6^2)/4. I'll leave you to the math.A1. Well if 6 i ducts= 12 ducks, then I would assume that 6 in ducts can roughly equal a ceramic duck.

The formula for calculating the area of an elliptical duct is: Area = π x (major axis/2) x (minor axis/2) Where the major axis is the longest diameter of the elliptical duct, and the minor axis is the shortest diameter.
answer is
Area of round duct is pi times radius squared.
