Moist air refers to a mixture of dry air and water vapor in which the dry air is treated as if it were a pure component. Ideal gas mixture principles usually apply to moist air. In particular, the Dalton model is applicable, and so the mixture pressure p is the sum of the partial pressures pa and pv of the dry air and water vapor, respectively.
