Nonetheless, you may multiply the air velocity by the duct place to get the air quantity. But, It isn't the right means of performing the air balancing work.
Then we will start to measurement the main ducts. To accomplish this ensure you start out at the main duct which is furthest away. Then we just add up the quantity movement premiums for many of the branches downstream of the.
