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 Technician or HVAC Tech or HVAC Mechanic or The AC Guy
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.
The essential duct work tools needed for a successful HVAC installation project include duct tape, tin snips, duct sealant, duct insulation, duct hangers, and a duct crimping tool. These tools are necessary for cutting, sealing, insulating, hanging, and connecting ductwork in a HVAC system.

Flex duct is a flexible, accordion-like duct made of plastic and wire, while rigid duct is a solid, inflexible duct typically made of metal. Flex duct is easier to install in tight spaces, but can be less efficient and more prone to damage. Rigid duct is more durable and efficient, but harder to install in tight spaces. The choice between the two depends on your specific HVAC system and installation needs. Consulting with a professional HVAC technician can help determine which type of duct is more suitable for your system.
That is a 16:9 aspect ratio.
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.
The purpose of a start collar in HVAC systems is to connect a flexible duct to a metal duct, allowing for proper airflow and distribution of heated or cooled air throughout a building.
Installing an HVAC duct fan in your home can improve air circulation, increase energy efficiency, and help maintain consistent temperatures throughout your living space.
the correct aspect ratio for 4x3 = 1.333 the correct aspect ratio for 16x9 = 1.777
The purpose of a starting collar duct in HVAC systems is to connect the main ductwork to a branch duct, allowing for the distribution of air to different areas of a building. It serves as a starting point for air to flow into the branch duct, ensuring efficient and effective heating or cooling throughout the space.
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.
The HVAC repairman used duct tape to help repair a loose aie ventilation duct.
