The same procedure was repeated for the test liquid by using the above formula viscosity of the test liquid could be determined. The time was counted for water to flow from mark A to mark B. Water was filled in to the viscometer up to mark A. The viscometer was mounted vertical position on a suitable stand. Η 1 can be determine using following equation.Īim: To determine the viscosity of liquid using Ostwald viscometer.Ĭhemical: Distilled water, Ethanol, Acetone.Īpparatus: Ostwald viscometer, Electronic balance, Stop watch.
Telegram Subscribe Facebook Follow Website Click here The time of flow of liquid under test is compared with time required for the liquid of known viscosity, the viscosity of unknown liquid. When the liquid flow by gravity time required for the liquid to pass between two mark A and B through the capillary tube is determined. Ostwald viscometer is used to determine viscosity of Newtonian fluid.
