To find the viscosity of a liquid using the oscillating disc method, you would typically place a disc in the liquid and oscillate it at a constant frequency. By measuring the torque required to keep the disc oscillating, along with other parameters like disc radius and frequency, you can calculate the viscosity using the equation specific to this method. This method is suitable for measuring the viscosity of Newtonian liquids.

How do you determine co-efficient of viscosity of pure liquid?
First of all, you have to break it apart. What is Viscosity?=thickness, stickyness, how it moves. To measure the thickness, you can either slide something down a slanted platform, or drop a marble into each jar of the liquids that you are comparing. To measure the stickyness, it would be a good idea to put cardboard on the two sides of the liquid, and stretch them apart, and see what happenes. Lastly, to measure how it moves: try and poor the liquids you are trying to compare down a slanted platform, and see how it moves.There isn't really something that can measure exact levels of viscosity.In conclusion, you can't get exact measurements of viscosity, but you are able to find out which liquid has the most viscosity, and which one has the less.Viscosity is the measure of fluidity a liquid exhibits - meaning how thick or how thin it is.Viscosity of liquid newtonian substances can be measured by measuring the time a liquid moves in a graduated tube from Point A to Point B at a given temperature usually 20oCCollodial substances can be measured using a graduated cup. The time taken for the liquid to drain out of the cup. the end time taken when the liquid stream breaks.In dilute solutions, an Ubhellode Tube is used. Here again, the time taken for a volume of liquid to pass from Point A to Boint B.In polymer melts, viscosity (melt viscosity) is done by measuring the torque of a synchronised stirrer in the molten polymer at a certain temperature.

How can one determine viscosity from density?
Viscosity cannot be directly determined from density. Viscosity is a measure of a fluid's resistance to flow, while density is a measure of how much mass is contained in a given volume. While there may be some correlation between viscosity and density for certain substances, viscosity is influenced by other factors such as temperature and pressure. To determine viscosity, specific tests or measurements need to be conducted using viscometers or other appropriate methods.
What is the relationship between viscosity and density in fluids?
Viscosity and density are related in fluids because viscosity is a measure of a fluid's resistance to flow, while density is a measure of how much mass is packed into a given volume of the fluid. Generally, fluids with higher density tend to have higher viscosity, meaning they are thicker and flow more slowly. Conversely, fluids with lower density typically have lower viscosity and flow more easily.
Where did viscosity come from?
Viscosity arises from the internal friction between molecules in a fluid as they move past each other. It is a measure of a fluid's resistance to flow. The level of viscosity depends on the type of fluid and its temperature.
Are Viscosity and Density related?
Yes, viscosity and density are related properties of a substance. Viscosity is a measure of a fluid's resistance to flow, while density is a measure of how much mass is contained in a given volume. Higher density substances tend to have higher viscosities, but the relationship is not always direct as it also depends on factors such as temperature and molecular structure.
How is the viscosity of the given liquid found by Meyer's oscillating disc method?
Three circular discs are rigidly fixed to a common axis followed by four fixed discs above, below and between the oscillating discs all at equal distances and close together. Then the surrounding gas can then be calculated from the logarithmic decrement of amplitude.
Which is a plausible reason for why a given liquid has a high viscosity?
A plausible reason why a given liquid has a high viscosity is that the compound has a high amount of hydrogen bonding. Examples of liquids with a high viscosity are lava, honey and corn syrup.
What are the relationship between viscosity and time of flow?
When a liquid is heated, it will generally become less viscous.
Relationship between flow time and viscosity?
The higher the viscosity, the lower the flow rate.
What is a plausible reason for why a given liquid has a high viscosity?
Strong intermolecular bonds such as those caused by polarity or large string molecules that 'tangle' causing the viscous nature.
Is copper viscous?
At Standard Temperature and Pressure, Copper is a solid metal.
What liquids have a high viscosity?
Liquids with high viscosity flow slowly, like honey. Liquids with low viscosity flow quickly, like water and vinegar.
What is oral chemotherapy?
Oral chemotherapy is given by mouth in the form a pill, capsule, or liquid. This is the easiest method and can usually be done at home.
How can you calculate volume when you know viscosity specific gravity of given liquid?
V = m / ρ Where V=volume m=weight ρ=density which is basically the same as Sg if reference to water at 4 degC
What would be the best method to separate these substances Given a homogeneous liquid mixture of sodium chloride (salt) and water?
Heating the solution water is deleted by evaporation.
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.
what other method of separating a liquid from a solid did you learn today other than filtration?
Methods of separating a solid and liquid rather than filtration. (a)When a solid and liquid are soluble,a method know as evaporation is used.When this mixture is heated,the liquid will evaporate and the solid will be left and obtained after evaporation. (b)When the mixture is insoluble,it is separated by use of decantation.The mixture is given some time to settle and the liquid is poured into another beaker and the the solid is left in the initial beaker.
