Chvorinov's rule

The total solidification time is the time required for the casting to solidify after pouring. This time is dependent on the size and shape of the casting by an empirical relationship known as Chvorinov's rule which states:

Tts=Cm(V/A)^n

Where Tts: Solidification time, min; V= volume of casting, cm3; A= surface area casting, cm2; n= an exponent usually taken to have value 2 and Cm is mold constant.
