Book excerpt: This method is, at a constant temperature, to measure the time for a certain volume of liquid, which flows through a calibrated glass capillary viscometer, under gravity. The product of the capillary constant of the viscometer multiplied by the flow time, is the kinematic viscosity of the measured liquid, at that temperature. At temperature t, the kinematic viscosity is represented by the symbol vt.
