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)
\[
v z=\frac{\rho * g * \delta^{2} * \cos (\beta)}{2 * \mu}
\]
