Formula 5.110
Maximum-velocity Vz-maximum of a falling film
Input(s)
$\rho$: Density $\left(\mathrm{kg} / \mathrm{m}^{3}\right)$
g: Gravitational Acceleration $\left(\mathrm{m} / \mathrm{s}^{2}\right)$
$\boldsymbol{\delta}$: Film Thickness $(\mathrm{m})$
$\mathrm{mu}$: Viscosity $(\mathrm{kg} /(\mathrm{ms}))$
$\beta$: Angle of inclination w.r.t direction of gravity (rad)
Output(s)
vz: Maximum Velocity $(\mathrm{m} / \mathrm{s})$
Formula(s)
$$ v z=\frac{\rho * g * \delta^{2} * \cos (\beta)}{2 * \mu} $$
