Air velocity across an air duct can be measured using tools such as anemometers which directly measure the speed of air flow. Alternatively, a pitot tube connected to a differential pressure gauge can be used to measure air velocity. Calibration of these tools and ensuring proper placement in the duct are crucial for accurate measurement.
The velocity pressure can be used to calculate the velocity of air in the duct using the formula: velocity = √(2 * pressure / air density). Assuming standard air density and converting 0.20 in w.g. to the appropriate pressure unit, the velocity of air in the duct would be approximately 903 ft/min.
The velocity of air flowing through a round duct can be calculated using the formula: Velocity = (2 * velocity pressure) / (air density). Given the velocity pressure of 0.20 in w.g., the air density needs to be known to determine the velocity.
The measure of an object's mass is called mass, and the measure of its velocity is called velocity.
Friction loss in ductwork is typically measured using the Darcy-Weisbach equation, which takes into account the duct size, velocity of the air flow, duct material, and length of the duct. By calculating the friction factor, you can determine the amount of pressure drop or loss due to friction in the ductwork. This information is essential for designing efficient HVAC systems.

The air is returning at a lower velocity, so you need a larger size duct.

To calculate the duct diameter, you need to consider the airflow requirements, velocity of air in the duct, and the friction losses. Use the Duct Sizing Chart or an online calculator to determine the appropriate duct diameter for your system based on these factors. It's important to ensure that the chosen diameter can handle the required airflow without causing excessive pressure drop.

answer is
velocity
Air velocity in ventilation systems
are a measure of angular velocity whereas metres per minute are a measure of linear velocity.
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
