Air Mass Flow Coefficient When No Outdoor Air Flow at Reference Conditions

Type: real number
Enter the air mass flow coefficient at the conditions defined in the Reference Crack Conditions object. 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 no outdoor air flow rate.
Unit: kg/s

Air Mass Flow Exponent When No Outdoor Air Flow

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 no outdoor air flow rate.
Unit: dimensionless
Minimum: 0.5
Maximum: 1.0
Default: 0.65
