Ohnesorge number
Input(s)
\(\mu\): Liquid Viscosity (Pa s or \(\mathrm{kg} /(\mathrm{m} \mathrm{s})\) )
L: Characteristic length (m)
\(\rho\): Liquid Density \(\left(\mathrm{kg} / \mathrm{m}^{3}\right)\)
\(\sigma\): Surface Tension \((\mathrm{N} / \mathrm{m})\)
Output(s)
Oh: Ohnesorge Number (dimensionless)
Formula(s)
\[
\mathrm{Oh}=\frac{\mu}{(\rho * \sigma * \mathrm{~L})^{0.5}}
\]
