Partial pressure formula of water
WebVapor pressure: Dalton's law of partial pressures states that the pressure exerted by a gas (its vapor pressure) is independent of the pressure of other gases; the vapor pressure e of the water vapor is given by the ideal gas law as where T is the absolute temperature in K and R v is the gas constant for water vapor. The vapour 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 vapour pressure is the pressure at which water vapour is in thermodynamic equilibrium with its condensed state. At … See more There are many published approximations for calculating saturated vapour pressure over water and over ice.
