Stanton number St

The Stanton number as modified by Westerterp, combines all relevant parameters which determine the cooling capacity of a chemical reactor. The Modified Stanton number is equivalent to the time constant of cooling in relation to the characteristic reaction time.

St = (U?A?tcharact.) / (V?ρ?cP)

The Modified Stanton number includes the common assumption that the product of density and specific heat capacity of the reaction mixtures as well as the product of overall heat transfer coefficient and heat transfer area remain approximately constant over the reaction period. Stanton numbers usually range from 3 for plant scale reactors to 20 for laboratory scale equipment.
