FAQ:
Q: What size duct for 1200 CFM?
A: A 901 to 1200 CFM fan requires an 8-inch minimum, and a 10- to 12-inch duct is recommended. At 1200 CFM and above, the duct size will depend on the type of fan motor and the length of the duct run, but it should never be smaller than 10 inches in diameter.
Q: How is ductwork sizing determined?
A: Look at the plate on your furnace to figure out how many BTUs it produces. Divide that number by 10,000 BTUs. Multiply that number by the amount of cubic feet of airflow per minute (CFM) your type of furnace produces. Divide your number by 10. … Calculate the size of your ducts vents by multiplying the length by the width. …
Q: How do you calculate the CFM of a duct?
A: To calculate Air Flow in Cubic Feet per Minute (CFM), determine the Flow Velocity in feet per minute, then multiply this figure by the Duct Cross Sectional Area.
Q: How many CFM in a 6 inch round duct?
A: The 0.10 design friction rate is the most commonly passed-down tradition of sizing ducts and the reason many assume a 6-inch duct delivers 100 cfm .
