Laminar flow takes place between parallel plates 10 mm apart. The plates are inclined at 45° with the horizontal. For oil of viscosity 0.9 kg/m.s and mass density is 1260 kg/m³, the pressure at two points 1.0 m vertically apart are 80 kN/m2 and 250 kN/m2 when the upper plate moves at 2.00 m/s velocity relative to the lower plate but in opposite direction to flow determine velocity distribution, max. velocity and shear stress on the top plate.

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.
