3 Overview

Kinematic viscosity measured mainly by thermostatic bath, temperature control system, timing system, composed of a capillary viscometer for Measuring kinematic viscosity of the liquid at different temperatures. At a constant temperature, the desired capillary measuring a volume of fluid flowing in a standard viscosity of gravity Between t, according to equation (1) calculate the standard viscosity fluid kinematic viscosity and its standard value, or according to formula (1) to calculate viscosity Meter constant. ν = Ct (1) Where. ν --- liquid kinematic viscosity, mm2/s; C --- viscometer constant, mm2/s2; T --- a volume of liquid flowing through a capillary time, s.
