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 saturation vapor pressure is the pressure at which water vapor is in thermodynamic equilibrium with its condensed state. At pressures higher than saturation vapor pressure, water would condense, while at lower pressures it would evaporate or sublimate.
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.
Saturated Vapor Pressure, Density for Water. ... ... Below are some selected values of temperature and the saturated vapor pressures required to place the boiling point at those temperatures.
1 cze 2018 · Bosen gave a formula for calculating the saturation vapor pressure of water with reasonable accuracy in the temperature range from −51.1° to 54.4°C . Langlois developed a fractional formula for computing the saturation vapor pressure of water and compared the results with the observed values in Byers (1959 ) and the formula in Berry et al ...
The graph shows how the saturated vapour pressure (svp) of water varies from 0°C to 100 °C. The pressure scale (the vertical one) is measured in kilopascals (kPa). 1 atmosphere pressure is 101.325 kPa.
