WebbThe theoretical value for water vapor is 19.6, but due to vapor condensation the water vapor density dependence is highly variable and is not well approximated by this formula. The pressure can be approximated by another exponent: Which is identical to the isothermal solution, with the same height scale Hp = RT0/gM. Webb25 sep. 2006 · Average density of water: 0.9823 g/mL.
