In rotating a thin circular disc submerged in a fluid, a torque has to be applied to the disc to overcome the frictional resistance of the fluid. Using dimensional analysis, show that where T is the applied torque and D is the diameter of a disc rotating at a speed N in fluid of viscosity u and density p.

Velocity distribution of a fluid in a sliding plate viscometer is used to measure the viscosity of the fluid. The top plate is moving with force (F) with a constant velocity (V) as shown in the Figure below. Force (Ft)= 5 N, Velocity (V) = 10 m/s, Temperature = 100°F. Top plate (Area » Length = 0.1 m and width = 0.05 m spaced by 0.001 m) is moving and the bottom plate is stationary. Determine: The viscosity of the fluid. Which fluid is this? Is this fluid more, or less viscous than water? ● IN FLOW N-L
