The performance of the plenum vaporizer depends extensively on the saturated vapour pressure of the volatile agent.
3.
A typical volatile agent, isoflurane, has a saturated vapour pressure of 32kPa ( about 1 / 3 of an atmosphere ).
4.
Saturated vapour pressure for any one agent varies with temperature, and plenum vaporizers are designed to operate within a specific temperature range.
5.
It can be used only for single-component mixtures ( eg . water with steam ), and can take values 1 ( for super-saturated vapours ):
6.
Relative humidity : The relative humidity of air is defined as the partial pressure of water vapour divided by the saturated vapour pressure at the same temperature and total pressure ( Siau, 1984 ).
7.
In Mason's formulation the changes in temperature across the boundary layer can be related to the changes in saturated vapour pressure by the Clausius Clapeyron relation; the two energy transport terms must be nearly equal but opposite in sign and so this sets the interface temperature of the drop.

Is it at least theoretically possible for certain meteorological conditions-saturated vapour in the air, warmer above, cooler below-to lead to a naturally occurring cloud chamber ?-would be fun to see the ghost trails of muons flipping through the air as you walk through the countryside . . . My understanding is of the lay type, by the way-for a start, I don't understand why it has to be alcohol vapour and not water vapour in the chamber-is it just because it's more volatile?
