A thin plate of very large area is placed in a gap of height h with oils of Example viscosities µ' and µ" on the two sides of the plate. The plate is pulled at a constant velocity V. Calculate the position of plate so that : (1) The shear force on the two sides of the plate is equal (ii) The force required to drag the plate is minimum. Assume viscous flow and neglect all end effects.

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
