Estimating Air Leakage

The amount of expected leakage can be calculated from the following equations:

Lv = 4005 x (Rp)1/2

Where,

* Lv = Leakage Velocity in feet per minute
* Rp = Room Pressure in in-WG


  L= 4005 x A x (Rp)1/2

Where,

* L = Air Leakage in Cubic Feet per Minute
* Rp = Room Pressure in in-WG
* A = Opening Area
