Ostwald’s Viscometer flow rate 75-100

A viscometer in which liquid is drawn into the higher of two glass bulbs joined by a length of capillary tubing.

Τhe time for its meniscus to fall between calibration marks above and below the upper bulb.

It is compared with that for a liquid of known viscosity.
