Falling cylinder

To eliminate part of the edge problem in the sliding plates, we can slide a cylinder inside a tube. If both ends are open and the gap is 

Band viscometer used for high shear rate testing of inks and coatings. 

Falling ( linder rbeometBis (a) open ends fm high viscosity samples and (b) closed end, free falling. 

Park and Irvine (1988) give relations for a power law fluid. They also demonstrate that one can easily change the effective density of the needle and thus Ta,x by using a hollow tube filled with various amounts of steel shot. In this way one can obtain an r) y) function.
