Hello, I'm a specialist in HVAC systems and ductwork design. When it comes to determining the flow rate of air through a duct, there are several factors to consider including the size of the duct, the type of duct material, the layout of the system, the number of bends and turns, and the static pressure within the system.
The Cubic Feet per Minute (CFM) is a measure of the volume of air that a duct can move in one minute. It is a standard unit used in the heating, ventilation, and air conditioning (HVAC) industry to size ducts and to determine the capacity of air handlers and fans.
For a 6-inch duct, the CFM it can handle is not a fixed number and will vary based on the aforementioned factors. However, as a general rule of thumb, a 6-inch round pipe can handle approximately 100 CFM. This is a rough estimate and assumes certain conditions such as smooth airflow and minimal resistance from bends or filters.
It's important to note that the actual CFM a duct can handle will be influenced by the system's design. For instance, if the duct has a lot of bends or if it's made of a material that creates more resistance, the CFM will be lower. Conversely, if the duct is part of a well-designed system with minimal resistance, it may be able to handle more than the estimated CFM.
Additionally, the Return Air Grills mentioned in your reference are part of the return air system, which is separate from the supply ducts that distribute conditioned air. These grills are typically sized to match the capacity of the HVAC system and are not directly related to the CFM of a 6-inch duct.
In summary, while a 6-inch duct can handle approximately 100 CFM under ideal conditions, the actual CFM will depend on the specific characteristics of the duct system and the design of the HVAC installation. It is always recommended to consult with an HVAC professional to accurately calculate the CFM for a given duct size and system configuration.

Return air grills are normally 8 inches high and the width of one or two. joist spaces. - 7 inch round pipe will handle approximately 150 CFM. - 6 inch round pipe will handle approximately 100 CFM.
