A cone-and-cup viscometer (see Fig. P3) is used to measure the viscosity of an oil which fills the clearance between the housing (cup) and cone. Cone rotates at 75 rev/s and geometry of the viscometer is given in the figure. If the moment applied to the shaft is measured to be T = 0.325 N . m, determine the viscosity u of the oil. Recommendation: The shear stress t acting on the surface of the cone should be expressed as a function of vertical coordinate z. N-s Ans: 1.012 m2 o= 75 rev/s 0.2 mm la-30 25 mm -OIL Fig. P3 1 of 2
