Parachor is a quantity related to surface tension that was proposed by S. Sugden in 1924. It is defined according to the formula:
Parachor is a quantity related to surface tension that was proposed by S. Sugden in 1924. It is defined according to the formula: P = \gamma^{1/4} M / (\rho_L - \rho_V),
where \gamma is the surface tension, M is the molar mass, \rho_L is the liquid density, and \rho_V is the vapor density in equilibrium with liquid. Parachor has a volume multiplier and is therefore extensible from components to mixtures. Parachor "has been used in solving various structural problems."
