Category: Units of dynamic viscosity

In fluid dynamics, the reyn is a British unit of dynamic viscosity,named in honour of Osbourne Reynolds, for whom the Reynolds number is also named.
The poiseuille (symbol Pl) has been proposed as a derived SI unit of dynamic viscosity, named after the French physicist Jean Léonard Marie Poiseuille (1797–1869). In practice the unit has never been

The poise (symbol P; /pɔɪz, pwɑːz/) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS). It is named after Jean Léonard Marie Poiseuille (see Hage
