Transcribed Image Text:
Figure below shows an idealized view of a liquid film of viscosity u that is draining under gavity down the side of a flat vertical wall. Such a situation would be approximated by the film left on the wall of a tank that was suddenly drained through a large hole in its base. The velocity profile at any distance x below the top of the wall is given by: pg y (2h-y) 24 where h-b() is the local film thickness. Show the steps applied and assumptions taken to derive this velocity profile. Also, find the mass flow rate per unit wall width (normal to the plane of the diagram).
