Hagen number
Input(s)
PG: Pressure Gradient \((\mathrm{Pa} / \mathrm{m})\)
\(\rho\): Fluid Density \(\left(\mathrm{kg} / \mathrm{m}^{3}\right)\)
L: Characteristic Length \((\mathrm{m})\)
v: Kinematic Viscosity \(\left(\mathrm{m}^{2} / \mathrm{s}\right)\)
Output(s)
Hg: Hagen Number (dimensionless)
Formula(s)
\[
\mathrm{Hg}=-\frac{1}{\rho} * \mathrm{PG} * \frac{\mathrm{L}^{3}}{\mathrm{v}^{2}}
\]
