Trouton's ratio

Physics

In physics, Trouton's ratio states that latent heat is connected to boiling point roughly by:

${\displaystyle {\frac {L_{vap}}{T_{boiling}}}\approx 87-88{\frac {J}{Kmol}}}$.

Rheology

In rheology, Trouton's ratio is the ratio of extensional viscosity to shear viscosity.[1] For a Newtonian fluid Trouton's ratio is 3.[2]
