Elasticity number ( \(El\) ) (dimensionless number)

Elasticity Number FORMULA

\(\large{ El = \frac { t \eta} { \rho r^2 } }\)         

Where:

\(\large{ El }\) = elasticity number

\(\large{ \rho }\)   (Greek symbol rho) = density

\(\large{ r }\) = pipe radius

\(\large{ t }\) = relaxation time

\(\large{ \eta }\)  (Greek symbol eta) = viscosity
