Water Vapor Temperature (°F, °C, K) ⇒ Pressure (kPa, PSI, mmHg, Bar, atm, torr) Quick Example: Vapor pressure of water at 20°C is 2.37 kPa, 0.34 PSI, 17.81 mmHg, 0.02 Bar, 0.02 atm, or 17.81 torr (from 2nd °C calculator and chart).
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.
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.
