We see that water at 25°C reaches vapor saturation pressure when the pressure equals 3.18 kPa. You can check the pressures expressed in other units as well; 25°C saturated water vapor pressure is equal to 0.46 PSI, 23.88 mmHg, 0.03 Bar, 0.03 atm, or 23.88 torr .
31 lip 2024 · With this vapor pressure of water calculator, you can find the vapor pressure at a particular temperature according to five different formulas. This calculator works for the standard 0-100 °C range as well as temperatures above 100 °C and below the freezing point.
Accurate thermophysical properties are available for several fluids. These data include the following: Density. C p. Enthalpy. Internal energy. Viscosity. Joule-Thomson coefficient. Specific volume.
Below are some selected values of temperature and the saturated vapor pressures required to place the boiling point at those temperatures. The pressures are stated in mega-Pascals, where a Pascal is a Newton per square meter, and as a multiple of standard atmospheric pressure.
The vapor pressure of water is the pressure exerted by molecules of water vapor in gaseous form (whether pure or in a mixture with other gases such as air). The saturation vapor pressure is the pressure at which water vapor is in thermodynamic equilibrium with its condensed state.
