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 do we calculate round duct area in cubic feet?
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.
Find the area of a sector. Do not round?
Because you will be using the number pi to find the area of the circle, some rounding will be required.
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 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.
What is the cross-sectional area of a 10-in round metal duct?
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.
What is the cross sectional area of a 10 inch metal round duct?
Cross-sectional area = pi*radius2
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 do you work out duct diametre?
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.
How can I find a residential duct cleaner who works evenings?
I work really long hours but need to get my ducts clean. How can I find someone who does residential duct cleaning in the evenings?
Do you round your answer when you find the area of a circle?
You would have to round since area will not be able to be represented without rounding.

Where can I find a good air duct cleaning service?
You can find a local air duct cleaning specialist in your area by checking your Yellow Page Book. They will also have coupons in the back of the book that you can use at various places.
Where can one find air duct cleaners in the Toronto area?
Toronto has a variety of air duct cleaner companies available for hire. A search will give contact information to Dave's Duct Cleaning, City Duct Cleaning and The Airduct Cleaning Company, to name a few.
What area of the duodenum where the common bile duct and the pancreatic duct empty is called?
The area of the duodenum where the common bile duct and the pancreatic duct empty is called the major duodenal papilla. This is where bile and pancreatic enzymes are released into the duodenum to aid in digestion.

How do you calculate square feet of a round duct?
Flatten it out then measure it with a ruler! ;)
