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 volumetric flow rate (volume per unit time) using the duct area.
While air temperature and duct shape can be important for other calculations (like density or pressure drop), they are not strictly necessary for calculating the volume flow
