a wide-hole with a finger, the fuel with a pear is drawn into the
narrow knee of the viscometer to the label М 2 between the
capillary and the expansion. After that the viscometer is turned
to normal position and wipes a narrow knee from the traces of
fuel.

viscosity of fuels
Viscometer is mounted vertically to the thermostat so
that the upper label M1 is below the water level in the
thermostat. During the test, the temperature in the thermostat is
maintained constant and even 20 С. Control it with a
thermometer. The water in the thermostat is mixed with a blade
mixer 10. The viscometer is kept in the thermostat for at least
15 minutes, so that the fuel takes a given temperature.
