Dean number

Input(s)

$\rho$: Density of the Fluid $\left(\mathrm{kg} / \mathrm{m}^{3}\right)$

$\mu$: Dynamic Viscosity $(\mathrm{kg} / \mathrm{ms})$

V: Axial Velocity Scale $(\mathrm{m} / \mathrm{s})$

$\mathrm{d}$: Diameter $(\mathrm{m})$

$\boldsymbol{R}_{\boldsymbol{c}}$: Radius of Curvature of the Path of Channel (m)

Output(s)

De: Dean Number (dimensionless)

Formula(s)

$$ D e=\frac{\rho * V * d}{\mu} *\left(\sqrt[2]{\left(\frac{d}{2 * R_{c}}\right)}\right) $$
