See Chvorinov's rule in All languages combined, or Wiktionary

Proper name

Etymology: Named after Czech engineer Nicolas Chvorinov, who described the rule in 1940. Etymology templates: {{etymon|en|id=metallurgy}} Head templates: {{en-prop}} Chvorinov's rule
  1. (metallurgy) An empirical formula used to calculate the solidification time of cast metal. The rule states that t=B(V/A)ⁿ, where t is the solidification time, B is a constant whose value depends on the material properties of the cast metal, V is the volume of the cast, A is the surface area of the cast that contacts the mold, and n is a constant that is usually around 1.5 to 2.
