 This thin film of fluid is difficult to quantify because its characteristics depend upon complex conditions of turbulence and viscosity—but when dealing with thin high-conductance barriers it can sometimes be quite significant.The previous conductance equations, written in terms of extensive properties, can be reformulated in terms of intensive properties.Ideally, the formulae for conductance should produce a quantity with dimensions independent of distance, like Ohm's Law for electrical resistance, formula_29, and conductance, formula_30.
