Question

The ________ method is duct sizing that considers the each duct section has the same air velocity.

Answer 1

The equal velocity approach for duct size assumes that the air velocity in each duct segment is the same.

How fast is the air moving through a duct?

The most common unit of air velocity (distance traveled in a unit of time) is feet per minute (FPM). The amount of air passing past a location in the duct per period of time may be calculated by multiplying the airflow by the area of the duct. The standard unit for volume flow is cubic feet per minute (CFM).

What happens when the size of ducts changes to the airflow?

• Result for an image The equal velocity technique for duct size makes the assumption that air velocity is constant across the entire duct system.

• The main lesson to be learned from this is that when air goes from a bigger to a narrower duct, its velocity rises. The velocity drops when it transitions from a shorter to a bigger duct. The flow rate or the amount of air passing through the duct in cubic feet per minute is the same in all scenarios.
