Principle 3

Liquid by external force, the resistance occurring between the liquid molecules called viscosity. Engler viscosity oil is again at a temperature from Engler viscometer

200mL outflow time required at the time and the ratio of water (i.e., water Viscometer values) the same volume of effluent 20 °C desired.

4 Instrument

Engler viscometer 4.1. 1.

5 Sampling

Samples were taken according to GB/T 1999 regulations.
