We start by establishing the momentum balance:
The specific shear stress profile can be determined by using the following boundary condition:
The following example is based on Problem 2.B1, assuming B = 2R

For a descendeing liquid film.
a) The equation that represents the velocity profile is derived as follows. We start by deriving the shear stress profile:
Assuming newtonian fluid:
