Capillary Tube Viscometer

Pasteur Pipette - Wikipedia
The liquid to be distilled is placed into a small reaction tube along with a boiling chip and heated to reflux one-half to two-thirds of the way up the inside of the tube. After squeezing the bulb to expel air, a pasteur pipette is inserted into the tube just below the level of the ring of refluxing liquid (into the vapor). ... Read Article

The Accuracy Of Measurements Of Viscosity Of Liquids
Precision attainable. The analysis of capillary measure­ ments is based on the Poiseuille equation, (1) where Pz is the pressure gradient along the capillary in the region where steady fl ow exists, Q the rate of fl ow (volume/time), YJ the viscosity, and r the radius of the (circular) capillary tube. In the usual case Pz ... Get Content Here

Capillary Rheometer - PTG
Capillary Rheometer The capillary rheometer (or viscometer) is the most common device for measuring viscosity. Gravity, compressed gas or a piston is used to generate pressure on the test fluid in a reservoir. A capillary tube of radius R and length L is connected to the bottom of the reservoir. Pressure drop and flow rate through this tube ... Read Full Source

Difference Between Ostwald And Ubbelohde Viscometers
Ostwald Viscometer or U-tube viscometer is a chemical instrument that is used to measure the viscosity of a liquid with a known density. This viscometer is named after the German chemist, Wilhelm Oswald. This viscometer is a U-tube with two bulbs separated by a capillary tube. The two bulbs act as reservoirs for the liquid. ...
