Lever rule



Using the lever rule one can determine quantitatively the relative composition of a mixture in a two-phase region in a phase diagram. The distances l from the mixture point along a horizontal tie line to both phase boundaries give the composition:[1]

Additional recommended knowledge

nαlα = nβlβ

nα represents the amount of phase α and nβ represents the amount of phase β.
