This equation Q = 840*A*√(dP) comes from the 1999 Ashrae Application Handbook, Fire and Smoke Management. Since I am interested on finding the A which is the room leakage I need to find a way to calculate the Q which is the differential airflow.
That is where the second part of the calculation...
Hello Everyone,
I am trying to calculate the openings of a sealed room according to a pressure drop in a specific time.
I have the following equation:
Q = 840*A*√(dP)
Q: differential airflow in liters/sec
A: room leakage in m2
dP: differential pressure in Pa...
