A Capilliary Viscometer measures the speed at which a lquid can be forced through a narrow tube (a capillary). Thicker liquids (high viscosity like treacle) will take a lot longer to squeeze through the tube than a thin liquid (like white spirit). If you take a fluid (liquid) like blood it could be put through a Viscometer like this to see if your blood was too thick or thin. Also it could be used to check if your engine oil met up to spec.

Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
What is construction of capillary viscometer?
A capillary viscometer is constructed from glass. Glass blowers make different styles of capillary viscometers with specific bulb and capillary diameters. These dimension determine the viscosity range of liquids which can be tested.
Construction and working of capillary flow viscometer?
A capillary flow viscometer, or Ostwald viscometer, consists of a U-shaped glass tube held vertically in a controlled temperature bath. It was named after its inventor, Wilhelm Ostwald.
What is the essential difference between Ostwald and Ubbelohde viscometer?
The essential difference between Ostwald and Ubbelohde viscometers is the method of measuring viscosity. Ostwald viscometer measures the flow time of a fixed volume of liquid through a capillary, while the Ubbelohde viscometer measures the flow time of a fixed volume of liquid out of a calibrated capillary. Additionally, the Ubbelohde viscometer is more accurate and suitable for measuring the viscosity of transparent liquids.
Who invented the first viscometer?
The first viscometer was invented by Sir William Thomson in 1866. His design was based on the principle of measuring the time it took for a liquid to flow through a capillary tube.
Where Ostwald's viscometer used?
Ostwald's viscometer is used to measure the viscosity of liquid substances, such as oils, paints, and polymer solutions. It consists of a capillary tube through which the liquid flows, and the time it takes for the liquid to flow through the tube is used to calculate its viscosity.
What is the basis for classification of redwood viscometer?
REDWOOD'S Viscometer is used to find out the viscosity of an standard rape oil and any of the fluids . The viscometers are classified into 4 types they are 1. Saybolt Viscometer 2. Engler Viscometr 3. Barbey Viscometer & 4. Redwoods Viscometer
How is viscosity measured?
viscometer
Why viscometer is used?
A viscometer is used to measure the viscosity of a fluid, which is its resistance to flow. This measurement is important in various industries such as food processing, pharmaceuticals, and manufacturing, where the viscosity of a fluid can affect product quality and performance. By using a viscometer, manufacturers can ensure consistency in their products and adjust formulations as needed.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
What is A and B in redwood viscometer?
In a redwood viscometer, A and B are constants used in the formula to calculate the viscosity of the fluid being tested. The formula is viscosity = A + B * time in seconds. The values of A and B are specific to the design of the redwood viscometer and are typically provided by the manufacturer.
Why the Ostwald's viscometer is kept vertically during experiment?
if we put viscometer horizontally, movement of liquid in the tube is not properly and time required by liquid which helps in calculation of viscosity of fluid
