You need at least these two measurements to calculate volume of air flowing through a duct. (Select all that apply) Select all that apply.
A. Velocity pressure B. Air Temperature C. Duct shape D. Duct area
To calculate the volume of air flowing through a duct, you need at least the following measurements:
A. Velocity pressure
D. Duct area
These two measurements allow you to determine the air velocity and then calculate the volume flow rate using the duct area. While air temperature and duct shape can influence other factors, they are not strictly necessary for calculating the volume
