Quiz I (A)
The viscous, incompressible and steady flow between the parallel plates shown in the
following Figure, is caused by both the motion o f the bottom plate and a pressure gradient,
dp/ dx. A n important dimensionless parameter for this type o f problem is
P = -{b^ l2piU){dpl dx) where ^ is the fluid viscosity. Find the dimensionless
velocity distribution {u/U).
