Liquid Ammonia - Thermal Properties at Saturation Pressure

Density, specific heat, thermal conductivity, viscosity and Prandtls no. of liquid ammonia at saturation pressure.

At atmospheric pressure, ammonia, NH3, is present as a liquid at temperatures below -33.6 °C (-28.5 °F). At 10 bara, the condensation/boiling point is 25 °C (77 °F). For more details about phase transitions, see ammonia phase diagram.

Below the tables, properties of liquid ammonia at saturation pressure as function of temperatur, are shown in figures.
