Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

fluid mechanics question

please solve with details and give reasons for steps if needed

Consider steady, incompressible, laminar flow of two Newtonian fluids sandwiched between
two infinitely large parallel plates. The fluids have different densities, different viscosities, and
they form a well-defined interface (i.e., they are immiscible). The lower plate is stationary
whereas the upper plate moves to the right at constant velocity U. There is no applied pressure
gradient pushing the fluid through the gap. The fluid is set into motion due to the movement of
the upper plate.
Determine the velocity at the interface in terms of U, 41, and Hz.
