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
You cannot "calculate" the front of a box. You can calculate its dmensions, or its area but calculating it does not make sense. As for calculating its size or area, the answer will depend on what information you have and what you require.
that depends on what size your duct is as it will vary depending on duct size
If you're only given the base, then you can't calculate the other leg. If you have any one of the following, then you can calculate all of the parts of the triangle: -- length of the other leg -- length of the hypotenuse -- size of either acute angle

A plenum is a meeting area where all participants are in attendance - as opposed to splitting off into small groups. Its size will depend on the number of people attending.
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.
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

you need to calculate the square footage, and then the area, and compare to the area of air cleaned by a purifier.

You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
Airwatts cannot be compared to miles per hour when considering air flow in vacuum systems. This is because the size of the ducts can vary (though there are some standards). With a given size duct, it is possible to discover the speed of the air flow if all other factors are known. A factor in computing airwatts is flow rate in CFM. Think one thing through: if air is moving at a given speed through a given duct, increasing the duct size (cross section) will cause air speed through the larger duct to go down for the same volume (in CFM) of air flow.
2.3mm in size
The air is returning at a lower velocity, so you need a larger size duct.
