DESCRIPTION:Lebo Molefe\nAbstract\nSurface roughness significantly modifie
 s the liquid film thickness when dip coating a solid surface at low veloci
 ty. To investigate the relative importance of slip atop the roughness comp
 ared to flow through the textured layer\, we experimentally measure film t
 hicknesses deposited on surfaces with roughness resembling disconnected po
 res in comparison with porous surfaces that allow flow through the texture
 s. Here\, the film thickness is calculated by modeling the flow with a hom
 ogenized boundary condition at an equivalent flat surface between the poro
 us region and outer film\, which accounts for both flow through the porous
  layer and slip at the equivalent surface. The model is found to agree wi
 th experimental data and requires no fitting parameters. Furthermore\, our
  model may be applied to arbitrary periodic roughness patterns\, facilitat
 ing characterization of surfaces found in natural and industrial coating p
 rocesses.
