1. An oil of density p and viscosity µ, drains steadily down the side of a vertical wall, as shown. After a
development region near the top of the wall, the oil film becomes independent of z
and flows with a constant thickness 8. Note that the wall is very large, extending
"infinitely" (compared to the thickness 8) in y and z directions. The vertical velocity
can be assumed to be the only component of flow velocity. The whole flow is taking
place out in the atmosphere and the atmosphere offers no shear resistance to the film.
