Duct Size Chart Cfm - Web see the ductwork size and cfm chart below for details. Web enter the air flowrate in cubic feet per minute (cfm) enter an internal duct size in inches (this must be limited to a maximum aspect ratio of 5:1 for the results to be valid) the resulting velocity and pressure drop per unit length are displayed in the blue box. Web below the calculator, we will demonstrate how the cubic feet per minute calculator works by solving one example using the calculator and cfm formula. Duct size chart coburns.xls author: So, identify the btu needed for each room and divide it by 30 to get the required cfm for the respective room. A duct sizing calculator uses cfm and other factors to determine what you need. It involves computer programs that take into account a lot of data including hvac system size, blower cfm rating, room sizes, the length of duct runs and much more.
