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.
Conversions
1 reyn = 1 lbf·sec·inches−2The relation between reyn and centipoise is approximately:
1 reyn = 6.89476 × 10 6 centipoiseIn SI units, viscosity is expressed as newton-seconds per square meter, or pascal-seconds. The conversion factor between the two is the same for stress:
1 reyn = 6890 Pa × sReferences
