Then, pull the line diagonally to the right and find the suitable duct diameter. 14″ round duct is less than ideal because the friction loss will be greater than 0.1 in.wg as the maximum airflow for 14″ round ducts is around 1027 cfm.Let's get started. 1. Calculate the CFM for Each Room. Most HVAC units are designed to have a 400 CFM of airflow for every 12000 BTU or 1 ton of cooling capacity and 12000 BTU divided by 400 CFM is 30. So, identify the BTU needed for each room and divide it by 30 to get the required CFM for the respective room. Each supply register should have 90 cfm because the living room requires a base total of 180 cfm. How many CFM does a 10 round duct have? 2000 cubic feet (0.94 m3/s) of air flow through a rectangular duct 10 x 12 inches.Duct Sizer ( Ductulator) for HVAC air ducts . It is designed for calculating and sizing duct dimensions according to air volume CFM, roughness, velocity, etc. It is available in SI and British IP units. Duct sizing needs a ductulator or software but this excel calculator performs the same calculations.If you consult the duct sizing chart here for flex and round ducts, you can see that for 2000 CFM airflow, you can choose a 20-inch metal round duct or either 36×10-inch or 30×12-inch rectangular duct. Hope this helps.The following is needed to determine the duct diameter: CFM and Velocity (CFM / V = AREA). Charts listed below show what duct diameter to use given a CFM and Velocity.
