Hydrostatic head viscometers, with

Hydrostatic head viscometers. (a) In the Ostwald design, liquid is filled exactly to mark C then sucked through the narrow capillary section to above mark A. The time for the meniscus to fall from. 4 to S is proportional to viscosity. (b) The side arm of the Ubbelehde design eliminates the need to fill with a precise volume, (c) The Cannon-Fenske design reverses the flow from (a) and is used for opaque fluids. The dark meniscus rises from A to B during the timing. (from Van Wazer et al., 1963). [Pg.366]
