Rheometer vs Viscometer

(II) A viscometer consists of two concentric cylinders, 10.20 cm ... | Study Prep in Pearson+

Problem 5: A common type of viscometer for liquids consists of a relatively large reservoir with a very slender outlet tube, the rate of outflow being determined by timing the fall in the surface level. If oil of constant density flows out of the viscometer shown at the rate of 5 10-7 m3/s, what is the kinematic viscosity of the fluid? Assume laminar, quasi-steady flow.
