Property plots: water and dry air
Compare liquid-water dynamic viscosity and dry-air density at selected discrete temperatures.
Conditions and limits
All points are at 101.325 kPa absolute. Water is single-phase liquid (10–90 °C); air is dry air (−20–100 °C, labelled supercritical_gas by CoolProp). Only listed discrete points are shown, with no connecting lines or interpolation; other pressures, moist air and phase-change states are not covered.
Plot lookup example
For liquid-water dynamic viscosity at 20 °C and 101.325 kPa absolute, find the marker and open the accessible table below to confirm 1.002 mPa·s. This is one discrete state; do not interpolate.
Liquid water dynamic viscosity
Each marker is a listed state; temperature is on the horizontal axis.

Values come from the project’s properties.json, generated using the CoolProp 8.0.0 HEOS model. Viscosity is shown in mPa·s; displayed digits do not imply model accuracy. These original charts are generated from those values.
