WebOstwald Viscometer (Capillary viscometer) which consists of two bulbs, one attached with a capillary tube and U-tube below the capillary tube while other bulb is attached to the other arm of U-tube at a level lower than the other bulb. The liquids of known densities are allowed to flow through the capillary maintaining the same differences of ... A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer. Viscometers can measure only constant viscosity, that is, viscosity that does not change with flow conditions. In general, either the fluid remains stationary and an object moves through it, or the object is sta… brown and green bathroom
