CFM stands for "cubic feet per minute" and is a measure of the volume of air moving through a fan or duct. SCFM is "standard cubic feet per minute," usually taken to mean CFM of "standard air," air at 68 degrees F and atmospheric pressure at sea level.The HVAC Veteran

HVAC is an abbreviation for heating, ventilation and air condition HVAC systems are the main mechanical infrastructure of a building and provide climate control functions.
The aspect ratio of a duct can be evaluated as the ratio of width to height. As the aspect ratio increases, vibration noise, friction and cost also increases.

Duct tape is a great to to seal off a HVAC duct. The tape is strong and works effectively for your needs. Duct tape can offer a tight seal for your duct.
That is a 16:9 aspect ratio.
the correct aspect ratio for 4x3 = 1.333 the correct aspect ratio for 16x9 = 1.777
The HVAC repairman used duct tape to help repair a loose aie ventilation duct.
The aspect ratio is the tires profile. For instance, a tire with a 60 aspect ratio means that the tires hight from tread to rim is 60% of the tires nominal width. The lower the aspect ratio # the wider the tire.

Obviously, an HVAC duct or pipe can pass through an electrical room, as described in the NEC. It cannot pass directly over or under panelboards, and elctrical equipment must be protected from condensation or drips form the pipe or duct.
The aspect ratio is the ratio of width to length, in this case either 3:5 or 5:3.
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.
