Elasticity Number

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

Elasticity Number FORMULA

\( Elasticity \; number  \;=\;   \frac { time  \;\;x\;\;   viscosity  } { density  \;\;x\;\;  pipe \; radius^2 }  \)

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

Where:

\(El\) = Elasticity number

\(t\) = relaxation time

\(\nu\) = viscosity

\(\rho\) = density

\(r\) = pipe radius
