Definition
"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. Viscometers only measure under one flow condition."
(Engineering Tribology, Gwindo W.Stachowiak et al)
As stated in the definition, the researcher's objective is to measure the viscosity of a liquid at a number of temperatures and find the viscosity v.s. temperature equation for the liquid.
Description of Procedure:
The inner cylinder is filled to the marker level and the outer cylinder filled so as to have sufficient height to give good heat transfer. The surrounding water is heated with an electrical heating coil. Heat is transferred to the inner cylinder by rotation of the blades of the agitator.
The first reading is taken by removing the stopper from the orifice. The recorded values were the water and test liquid temperatures and the time to collect 50cc of the liquid being recorded. Both the beginning and end temperatures are noted.
The collected 50cc of liquid must be put back into the inner cylinder and the used cylinder inverted to empty completely. The level of the sample is checked as, if more of the liquid is needed it would be added. The temperature is then raised and the agitator is used again continuously. This is done until the liquid is brought within 1 degree of the water temperature. The same parameters were again measured. This procedure is repeated for 5 samples in total (at least).

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
Can you use a steam cleaner to clean redwood deck?
Nah, just use some rags and Bleach, or if you don't wanna risk getting hurt from its chemicals, just use soap and water. But it depends how big it is :L
When is redwood and sequoia bark thickest?
when it has matured
What organisms is most likely 50 meters in size?
Redwood trees are one species.
How tall is the worlds tallest living tree?
A giant redwood in California's Redwood National Park is the tallest tree on earth. You can look out the top-floor of a building 35 stories high- and still not see the top! The tree was named Hyperion, and it is about 379.1 feet tall!

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
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.
What is the use of redwood viscometer in your daily life?
I don't even know what it is so obviously it does not feature in my daily life.
Who invented redwood viscometer?
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.
What is the length and diameter of redwood viscometer?

Viscosity of disel by redwood viscometer?
Because it is the most convenient device as far as protection and accuracy is concerned.
What are the errors of redwood viscometer experiment?
time was not calculated at the right point so the poits of the graph were chaned
Why you heat oil indirectly in redwood viscometer experiment?
SO that the oil cup gets uniformly heated from all the sides
Where is use viscometer?
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.
Why there was a need of redwood viscometer?
A standard British-type viscometer in which the viscosity is determined by the time, in seconds, required for a certain quantity of liquid to pass out through the orifice under given conditions; used for determining viscosities of petroleum oils.
Why is Ostwald viscometer more important?
The Ostwald viscometer is important because it can accurately measure the viscosity of liquids, which is crucial in various industries such as food, pharmaceuticals, and manufacturing. It is simple in design and easy to use, making it a popular choice for viscosity measurements in research and quality control processes.
