Abstract : Expressions are derived for the torque exerted on a finite cylindrical disk which executes torsional oscillations about the cylindrical axis while immersed in a viscous fluid parallel to a rigid plane boundary. Relations for the total torque of the fluid are given in terms of the period and decrement of disk oscillation for small, large, and intermediate separation distances between the disk and the rigid plane boundary. Mathematical relations and graphic results are presented in a form intended to aid investigators in studying the properties of fluids flowing in narrow channels. (Author)
