Reyn
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.[1]
Conversions
[edit]By definition,
- 1 reyn = 1 lbf s in−2.
It follows that the relation between the reyn and the poise is approximately
- 1 reyn = 6.89476 × 104 P.
In SI units, viscosity is expressed in newton-seconds per square meter, or equivalently in pascal-seconds. The conversion factor between the two is approximately
- 1 reyn = 6890 Pa s.
