Rate-dependent slip of Newtonian liquid was analyzed at smooth surfaces. The analysis was performed on Newtonian fluids placed between molecularly smooth surfaces with vibrated spacing. Failure of prediction in three liquid-solid system based on the classical no-slip boundary condition of fluid flow was also demonstrated. It was found that hydrodynamic forces became upto 2-4 orders of magnitudes with increasing flow rate and partially wetted surfaces.
