[Equest-users] Pressure difference for CRACK infiltration calculation

[Ng, Lisa]

Hello,

In Vol 2 (dictionary) of the DOE-2.2 documentation, infiltration = INF-COEF*dP^(1/2)*L. I know the outside pressure can be found in the weather file but where does the inside pressure (to calculate dP) come from? Is it calculated or assumed?

Thanks,
Lisa
