Q.5 (20 Pt.) Castor oil at 25°C fills the space between two concentric cylinders of 0.2 m and 0.1 m diameters with height of 0.1 m. when the outer cylinder remains stationary and the inner cylinder rotate with a force F. Where A is the area of inner cylinder, U is the inner cylinder velocity, L is the distance between the cylinders, is the angle of deformation between the cylinders. Assume steady state conditions. (a) Drive an equation to calculate shear stress as a function of dynamic viscosity, velocity, the distance between the cylinders, and the area. (b) Calculate the force that is required to drag a very thin cylinder at a velocity of 0.5 m/s. The viscosity of Castor oil is 0.986 (kg / m. s). O h 00 ןןן To
