1- Two immiscible liquids flow between a fixed lower plate and a moving upper plate. There is no seperating plate between two liquids. The thickness of the liquids layers and their viscosities are shown in the figure. a) Find the velocity profile for each liquid. b) Sketch the velocity profile for each liquid. c) Find an expression for the velocity of the interface line. d) Make comment on the interface velocity expression (How it changes with changing the dependent parameters.) Hint: Recall the boundary conditions for the single liquid flow between two plates. For this question the interface velocity and interface shear stress is equal for both fluids. X Fixed V
