1) Shell Momentum Balance For laminar flow of a fluid (,) through horizontal, infinite plates as shown in the figure (flow only in x direction). 1) perform a mass balance (5 points). 2) Identify the forces acting on the shell with proper direction (5 points) 3) Perform a shell momentum balance and get to the differential equation for velocity [Hint - You need to know the newton's law of viscosity] (10 points). 4) What are the boundary conditions to be used for velocity (5 points). 5) Solve for the velocity profile as a function of y. (5 points). For this problem you can assume dP/dx0
