We already know all these values Therefore if we fall the figures in we get a solution of 0.718 pascals. So just include that for the desk. (Check out the online video at the bottom in the web site to determine how to work out that).
For those who’re working on current HVAC models, create down the airflow of each diffuser you’ve just measured with all your helper with your drawing.
