Hedstrom Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Hedstrom number, abbreviated as He, a dimensionless number.


Hedstrom Number formula

\(\large{ He = \frac{ \left(\rho\;d^2\right) \; \tau  }{ \mu^2 }  }\)   


\(\large{ He }\) = Hedstrom number

\(\large{ \rho }\)   (Greek symbol rho) = mass density of fluid

\(\large{ \mu }\)  (Greek symbol mu) = dynamic viscosity

\(\large{ d }\) = pipe inside diameter

\(\large{ \tau }\)  (Greek symbol tau) = yield point of fluid
