fluid has viscosity of # and a radius of Rs. Assume steady,incompressible, fully developed flow in the x-direction only. a. Obtain a simplified form of Navier-Stokes equations in cylindrical coordinates for the flow. b. State the boundary conditions for the flow. (Hint: Velocity and shear stress at the interface between the two fluids must be continuous.) c. Solve for the velocity profiles in the fluids and sketch it.
