chung(target[, temperature, mol_weight, ...])

Uses Chung et al. [1] model to estimate viscosity for gases at low pressure (much less than the critical pressure) at conditions of interest.

reynolds(target, u0, b[, temperature])

Uses exponential model by Reynolds [1] for the temperature dependance of shear viscosity

water(target[, temperature, salinity])

Calculates viscosity of pure water or seawater at atmospheric pressure using Eq.
