    Verifying Dimensionality of Fall Velocity Equation

    The equation for the fall velocity (terminal velocity) of a particle of a material in a viscous medium has been derived from theory as: Vt = gd^2(Pp - Pm) / 18 u Where: Vt is the terminal velocity in m/s; g is the acceleration due to gravity; d is particle diameter in m; Pp and Pm are the...
