(rule of mixtures) Properties of binary mixtures lie between the corresponding properties of the pure components and are proportional to the volume fractions v (sometimes weight or mole fractions) of the components. For example, the, density ρ of a blend is given by:
$$\rho _{\rm m} \,{\rm =}\,\rho _{\rm 1} {\rm }v_{\rm 1} {\rm + }\rho _{\rm 2} {\rm }v_{\rm 2} \,{\rm= }\,\rho _{\rm 2} {\rm + (}\rho _{\rm 1} {\rm- }\rho _{\rm 2} {\rm )}$$
