A disc is spun between two parallel plates of a platform balance and the deflection is noted. A metal sheet and a disc are mounted parallel in a container of fluid. Rotate the disc and observe the displacement of the sheet by projection. As the outer cylinder is rotated, the drag induced motion of the inner cylinder is observed by optical lever magnification. 2C30.25 viscosity of oil PIRA 1000 2C30.25 viscosity of oil Fm-2 Invert several sealed tubes filled with oil.
