_{Psychrometric calculator. To solve for humidity ratio, the calculations assume that moist air is a mixture of independent perfect gasses, water vapor and dry air: Dry air: p da V = n da RT. Water Vapor: p w V = n w RT. Combining these two equations using the perfect gas equation: pV = nRT: (p da + p w) V = (n da + n w) RT. }
