Question:
1) Calculate the torque per unit length required to turn the cylinder (calculate the shear stress first, in cylindrical coordinates ) and 2) Determine the velocity profile in the gap in dimensionless form. based on flow between two concentric cylinders, which is driven by rotation of one of the cylinders. The inner cylinder of radius a rotates at angular velocity and the outer cylinder of radius a is stationary.
