In fluid dynamics, the Reyn is a British unit of dynamic viscosity. Named in honour of Osbourne Reynolds, for whom Reynolds number is also named [1]
One Reyn is:
- 1 Reyn = 1 lbf·sec·inches-2
Relation between Reyn and centipoise is approximately:
- 1 Reyn = 6.89476 × 10 6 centipoise
In 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 × s
