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.
How do you calculate area of rectangular duct 90 degree elbow?
To calculate the area of a rectangular duct 90-degree elbow, first determine the cross-sectional area of the duct sections before and after the elbow. Measure the width and height of the duct to find the area using the formula: Area = Width × Height. For the elbow itself, you can typically ignore its contribution to the area, focusing instead on the straight sections, as the elbow primarily changes direction rather than cross-sectional area. Ensure to account for any additional factors like flow dynamics if necessary.
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 to calculate duct area?
Oh, dude, calculating duct area is like figuring out how much space your air is gonna flow through. Just multiply the width by the height of the duct to get the area. It's not rocket science, but hey, it's important for making sure your air conditioning doesn't end up like a sad deflated balloon.
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 cfm in duct?
To find cubic feet per minute (CFM) in a duct, you can use the formula: CFM = Air Velocity (feet per minute) × Duct Area (square feet). Measure the air velocity using an anemometer and calculate the duct area by multiplying the width and height for rectangular ducts or using the formula for the area of a circle (π × radius²) for round ducts. Multiply these two values to get the CFM. Alternatively, you can use duct flow measurement devices or tools for an accurate reading.
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

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.
