Select suitable velocities in the main and branch ducts. 2. Find the diameters of main and branch ducts from airflow rates and velocities for circular ducts. For rectangular ducts, find the cross – sectional area from flow rate and velocity, and then y fixing the aspect ratio, find the two sides of the rectangular duct. . From the velocities and duct dimensions obtained in the previous step, find the frictional pressure drop for main and branch ducts using friction chart or equation
