What is the difference between HVAC diffuser's neck velocity and face velocity?
In HVAC terminology, a diffuser's neck velocity is defined as the velocity of air traveling through the duct work to the air outlet or inlet. The difference of the face velocity is this is a measurement of fume hood performance.

How can measure the velocity in the duct?
existing duct = velometer (Google velometer). Calculate velocity if volume is known and the size of duct volume (cubic feet) multiplied, square feet feet of duct, IE. 1000 cubic foot of air * 12" x12" square duct = 1000 cubic feet * 1sq. foot = 1000 feet per minute
How fast does air with a velocity pressure of 0.20 in w.g. move through a round duct?
1800 ft min
What is air velocity of air flow in an air conditioning room?
Not sure I understand your question, Velocity is the speed in feet per minute the air is moving. This is usually associated with the duct system. In a room the velocity of the air entering the room at the supply grille/register, would be about 500 to 700 fpm (feet per minute), in the occupied area of the room velocity should be less then 50 fpm.

Why the return duct of AHU is larger than supply duct?
The air is returning at a lower velocity, so you need a larger size duct.

How can you visually determine if there is ample air flow across a duct-mounted electric heater?
To visually determine if there is enough air flow across a duct mounted electric heater, you should tape a piece of cardboard to it. A small piece that can flutter in the flow of the air. If it moves wildly, there is enough air.

What is CFM in HVAC system?
Short for cubic feet per minute, a measurement of the velocity at which air flows into or out of a space.

What type of duct would you fit on a warm air unit?
a se duct and a u duct
