The figure below shows the geometry of a rheological experiment. A fluid lies between R₀and R_i, where R_i= 16.00 mm and R₀= 17.00 mm. The gap between the two cylinders can be modeled as two parallel plates separated by a fluid. The inner cylinder is rotated at 6000 rpm, and the torque is measured to be 0.03 Nm. The length of the inner cylinder is 33.4 mm. Determine the viscosity of the fluid. We can assume that the inner cylinder is completely submerged in the fluid, that the fluid is Newtonian, and that the viscous end effects of the two ends of the inner cylinder are negligible.
