Look up generated dry-air density and viscosity at selected temperatures and 1 atm. Transfer a reviewed point to Duct Size without silently interpolating.
QUICK LOOKUP
Search within the verified subset. Numeric sizes match complete designations; a nearby size is a candidate, not an exact match.

Dry-air model point: Generated dry/humid air thermophysical points — CoolProp 7.1.0 PropsSI Air at 101325 Pa; generated selected point · verified 2026-10-07 · source value -10 °C dry air.
Pinned offline PropsSI density and dynamic viscosity; ν=μ/ρ×10^6 cSt. Store unrounded generated outputs and convert display units without changing the point.
CHECK THE METHOD
Worked example
At 20 °C and 101325 Pa, dry-air density is about 1.2046 kg/m³ and ν about 15.1 cSt. Select the actual generated point before review/apply.
Dry-air model only; humid or pressurized air changes density. Choose measured/appropriate design properties where available. Viscosity units cSt are mm²/s.
TRACEABLE DATA
Sources, scope & verification
Dataset v1.3.0 Last verified:
Nine generated dry-air points from −10 to 50 °C at 101325 Pa. Pinned model revision is recorded in full provenance. No interpolation or altitude correction.
Values are curated product facts or generated scenarios. Paid standards, complete catalogs and source diagrams are not reproduced. A verification date applies to this documented subset.
