A plate is pulled upward from a pool of liquid with velocity, V, entering a thin liquid film on the surface of the plate. The flow is assumed to be laminar and the film thickness, H, constant. Using a coordinate system located on the plate at the surface of the pool, complete the following:
a. Dram and sketch the system. Include coordinate system in your sketch.
b. In what direction is flow and shear stress?
c. What assumptions can you make regarding this system?
d. What are your boundary conditions for this system?
