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.
The redwood viscometer was invented by Norman Henry Redwood, a British chemist and engineer, in the late 19th century. It was designed to measure the viscosity of liquids, particularly petroleum and related products.
The Saybolt viscometer was invented by J. W. Saybolt in the early 20th century as a method to measure the viscosity of petroleum-based fluids like oils. It is commonly used in the petroleum industry to determine the flow properties of various fluids.
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.
A falling ball viscometer measures the viscosity of a fluid by timing how long it takes for a ball to fall through the fluid. The viscosity of the fluid affects how quickly the ball falls, with more viscous fluids causing the ball to fall more slowly. By measuring the time it takes for the ball to fall, the viscometer can calculate the viscosity of the fluid.
A viscometer is a device used to measure the viscosity of a fluid. It can be used in various industries such as food processing, pharmaceuticals, and petrochemicals to ensure product quality and consistency. It is commonly found in laboratories and production facilities where viscosity control is important.

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
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
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.
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.
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
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.
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.
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
