For the cone-plate viscometer in Fig., the angle isvery small, and the gap is filled with test liquid μ. Assuminga linear velocity profile, derive a formula for the viscosity μin terms of the torque M and cone parameters.4748

or a sliding plate viscometer of the type we have discussed in class, it is found that when the distance between the plates is 2 mm, a shearing stress of 150 Pa develops at the upper plate when it is pulled at a velocity of 0.5 m/s. The viscosity of the Newtonian fluid between the plates is:

The liquid fills a space between two parallel plates, 1.4 cm apart.What force is required to move one plate past the other stationary plate with a velocity of 3.47 cm/s, if the moving plate has an area of 3.8 m2?Give your answer in Newtons unit.Viscosity is 5.13x 10-3 Pa.s
