Air Mass Flow Coefficient When Opening is Closed

Type: real number
Defined at 1 Pa pressure difference. Enter the coefficient used in the following equation: Mass flow rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when opening is closed.
Unit: kg/s-m

Air Mass Flow Exponent When Opening is Closed

Type: real number
Enter the exponent used in the following equation: Mass flow rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when opening is closed.
Unit: dimensionless
Minimum: 0.5
Maximum: 1.0
Default: .65

Sloping Plane Angle

Type: real number
Sloping plane angle = 90 is equivalent to fully open.
Unit: deg
Maximum: 90
Default: 90

Discharge Coefficient

Type: real number
The Discharge Coefficient indicates the fractional effectiveness for air flow through the opening at that Opening Factor.
Unit: dimensionless
