Online calculator to compute the friction loss in air ducts. THREE STEPS TO SIZING AIR DUCTS. 1. Calculate the CFM needed for each room. HOW: Perform a whole house and room-by-room load calculation (Manual J). Then apply the following formula: Room CFM = (Room Load / Whole House Load) X Equipment CFM. *A room-by-room load calculation must be performed in. When sizing a duct system the designer will usually choose a design friction rate. • This is the desired friction loss in inches w.g. per 100 ft. of equivalent length (in. w.g./100 ft. E.L.) of duct. • The design friction rate is generally determined based on the velocity of the air in the first section of ductwork. • Most designers use a. Heating & Cooling Quick-sizing Table.
