1. Two large fixed parallel planes are 12mm apart. The space between the surfaces is
filled with oil viscosity 0.972 N.s/m2

. A flat thin plate 0.25m2

area moves through the

oil at a velocity of 0.3 m/s. Calculate the drag force:
i. When the plate is equidistant from both the planes, and
ii. When the thin plate is at a distance of 4 mm from one of the plane surfaces.

12-9 Two large parallel plane conducting plates are a distance d apart. The region between them is filled with two l.i.h. materials whose surface of separation is a plane parallel to the plates. The first material (with properties σ1 and Ɛ1) is of thickness x, while the second material (σ2, Ɛ2) has thickness d - x. There is a steady current between the plates that are kept at constant potentials of φ1 and φ2. Find the potential at the surface...

Two large parallel copper plates are 3.60 cm apart and have a uniform electric field of magnitude E = 7.98 N/C between them (see the figure).

Consider two-dimensional incompressible plane viscous flow between parallel plates a distance 2h apart, with the origin along the centerline. The plates are very wide and very long, so that the flow is essentially axial. The present case is where the upper plate moves at velocity V but there is no pressure gradient. Neglect gravity effects. Determine the velocity profile for this flow.
