Viscosity measurement method

2023-12-08

The kinematic viscosity tester of Wuhan UHV can help many power workers to carry out various power tests more conveniently.There are three measurement methods for viscosity measurement: dynamic viscosity, kinematic viscosity, and conditional viscosity.1. Dynamic viscosity: the resistance generated when two liquid layers are separated by 1 cm, their area is 1 (square centimeter), the relative moving speed is 1 cm/s, and the unit is grams/mile/second. 1 g/cm·s = 1 equilibrium General: The industrial unit of dynamic viscosity is expressed in equilibrium.2. Kinematic viscosity: When the temperature is T°C, the kinematic viscosity is represented by symbols. In the International System of Units, the unit of kinematic viscosity is ST, which is square meters per second.) means that the unit is millimeters per second (i.e., 1CST = 1M2/s). Kinematic viscosity is widely used in the viscosity determination of liquid petroleum products such as jet fuel, diesel, and lubricating oil, dark petroleum p
