viscosity $\backslash$mu that flows steadily down the wall. The volumetric flow

rate of the liquid per unit width of wall is Q $.$

Assumptions:

There is only one nonzero velocity component, v$\_($x$),$ and this

does not vary in the x direction.

The gas exerts a negligible shear stress on the liquid.

Derive an equation for v$\_($x$)$ and Q as a function of $\backslash$rho $,\backslash$mu $,\backslash$delta $,$ g$,$ an$($d$)/($o$)$r y$.$
