Relative Viscosity often refers to that of a Polymer Solution and is defined as the ratio of the viscosity of the solution to the pure solvent. It is calculated experimentally by measuring the time that it takes for the pure solvent to pass through a certain tube, in certain conditions , and compari…ng it with the time it takes for the solution to pass through the same tube, in the same condition.. The term Apparent Viscosity is used when you calculate the viscosity of a non-Newtonian fluid by applying equations that are derived for the viscosity of a Newtonian fluid. So it is not the actual viscosity.. I hope this answers your question. ( Full Answer )
Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules .
Friction is due to resistance between two solid surfaces where viscosity is due to cohesion or adhesion between two liquid surfaces.
Viscosity is a property of liquids, showing that liquid's resistance to flow. A liquid with a high viscosity would mean it flowed slowly. A liquid with a low viscosity would mean it flows rather quickly.
Viscosity is a measure of the resistance of a fluid which isbeing deformed by either shear stress or tensile stress. Ineveryday terms (and for fluids only), viscosity is "thickness" or"internal friction". Thus, water is "thin", having a lowerviscosity, while honey is "thick", having a higher viscosi…ty. Putsimply, the less viscous the fluid is, the greater its ease ofmovement (fluidity). ( Full Answer )
A viscosity enhancing agent basically thickens the fluid. However;a suspending agent performs two functions, one is that of aviscosity enhancing agent, secondly forming a film around theparticle and decreasing interparticle attraction.
viscose (also known as viscose rayon) is a group of fabrics and yarns produced by extruding cellulose solution through holes in a spinneret, then coagulating the resulting filaments in an acid (the viscose process). There are several different sort of viscose fibres made by modifying this process, e…g crimped, hollow, high tenacity (stronger).. So viscose rayon is a particular type of cellulose fibre made using the viscose process, and it's also often called just 'viscose' or just 'rayon', because it's the commonest kind of rayon. Other kinds of rayon are cuprammonium rayon and acetate rayon. ( Full Answer )
Surface tension is the amount of attraction the surface of an object has. Surface tension is easily demonstrated by observing a pool of water. Put your finger in the water and slowly... i mean "slowly"... pull your finger away and you will see the water is actually attracted to your finger and th…e water will stay on your finger as you pull your finger off the pool of water. This is because of surface tension. Viscosity is the resistance of a liquid flow. A high viscosity means the liquid is thicker and does not move as readily. (And technically solids have an infinite viscosity because they do not "flow"). A high viscous liquid would be like syrup. A low viscous liquid would be like water. Now... a high viscous liquid (like syrup) has a higher surface tension than a low viscous liquid. Do the "finger" demonstration with syrup. You will notice that syrup (being more viscous) will actually be attracted to your finger more than water is. Once you put your finger in a pool of syrup and bring it out... more syrup will be still on your finger. If you relate the water and syrup demonstration you will see that a higher viscosity means a greater surface tension and a lower viscosity means a lower surface tension. ( Full Answer )
Both are thicker and slower to flow when both are increased. So it is a relation to number of particles.
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
During a quiet eruption lava flows from vents, setting fire to, and then burying, everything in its path. During an explosive eruption, a volcano can belch out hot clouds of deadly gases as well as ash, cinders, and bombs
There is no relationship because water, pours easily and has a low density and syrup has a high viscosity at room temperature when heated it will pour quite easily while the density stays the same.
Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules. Of course, viscosity is resistance of flow and surface tension of lateral force but viscosity is s display of frictional force during laminar flow caused due to intermolecular forces. T…he surface tension is a function of cohesive forces generated by intermolecular forces among similar molecules. Very rightly since both the parameters are dynamic in natures and hence a 3rd parameter noted as friccohesity is most advanced version of the contribution of the intermolecular forces operational in liquid dynamic behavior. The friccohesity along with surface tension, viscosity, wetting coefficient, interfacial tension are measured with borosil mansingh survismeter. ( Full Answer )
Different Liquids have Different Viscosities because some liquids are thicker, stronger, thiner, etc. than others, so they have different resistance of different fulids.
Surface tension is the elasticlike force existing in the surface of a body or a liquid, tending to minimize the area of the surface, caused by asymmetries in the intermolecular forces between surface molecules and viscosity is defined as the property of a fluid that resists the force tending to caus…e the fluid to flow or the measure of the extent to which a fluid possesses this property.

I'm guessing you're talking about a disc viscometer, in which case the higher the viscosity, the higher the measured torque.
What is the difference in silica content and viscosity between light colored and dark colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
The viscosity of a substance is dependent on the ability of itsparticles to rearrange and move past each other. This is affectedby their shape and size and by the forces of attraction betweenthem, The greater the forces, the greater the viscosity. Forinstance, the forces between molecules in the hyd…rocarbons whichmake up crude oil are van der Waals forces. They are larger forlonger molecules. Thus when you separate out the different sizedmolecules by fractional distillation, one difference you findbetween the fractions is that viscosity increases with molecularsize. ( Full Answer )

dynamic vscosity is the resistance of fluid when it is subjected to a force or shear stress......while the knematic viscosity is the sistance to flow when it is subjected to force of gravty
Viscose and modal both are semi synthetic fibre, where the modal has more wet strength than viscose and have less shiny than viscose
What is the difference in silica content and viscosity between light-colored and dark-colored magma?
magma that is to high in the silica produces light-colored lava. low silica flows readily and produces dark-colored lava.
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
Explain why the effect of temperature on the viscosity of gases differs from the effect of temperature on the viscosity of liquids?
The effect of temperature on viscosity of a liquid, according to particle model, as temp. increases viscosity decreases.The effect of temperature o viscosity of a gas, according to particle model, as temp. increases viscosity increases.
Some fluids are more denser than other fluids. For example, shampoo is more denser than Ketchup or oil or water. Therefore, it has a higher viscosity! The thick/denser/sticker a fluid is the higher the concentrtation of viscosity. Here is a range of some fluids put from high viscosity to low concent…ration of viscosity: 1: Shampoo 2: Ketchup 3: Corn oil 4: Water Water has a really low concentration of viscosity.

Shear rate and viscosity are related to each other. According to shear rate and viscosity we can classifying the materials especially paints. Fluids are divided into two types like 1.NEWNONION FLUIDS and 2.NON NWETONINON FLUIDS based on shear rate and viscosity. In fluids if there no change in v…iscosity with respective shear rate, such type fluids are known as nwetonion fluids. Viscosity changes with respective shear rate such type of fluids are known as non nwetonion fluids. ( Full Answer )
Viscosity is the thickness of a substance; how easily it flows. Molasses> very viscous Water-> not so viscous
Absolute viscosity measures the resistance of a fluid to change shape and/or flow. Relative viscosity is mostly used to compare one fluid to another, as when you are trying to dilute a fluid with another one like a solvent.
the more viscus the liquid( higher viscosity), the more time it takes to flow through a hole, given the same pressure difference.
Viscosity varies from one lava to another lava and from one magma to another magma. Magma and lava could have the same viscosity, or be completely opposite on the viscosity spectrum.
Stickiness vs Friction Adhesiveness is the measure of how much one type of substance "sticks" to a different kind of substance. i.e., tape has a higher adhesiveness than paper. Viscosity is how "thick" a substance is. i.e., honey has a higher viscosity than water.
they are two truly different concepts. The density is a measurement of the molecular weight of the composition. In simpler words, density = number of molecules x molecular weight/volume occupied, while the viscosity is a measurement of the inter-molecular forces and molecule shapes. Viscosity tells …you the "friction" between two layers of the given fluid, while density varies slightly with temperature, viscosity changes rapidly. Both density and viscosity decreases with temperature, but viscosity mostly has an exponential relationship with temperature. Density holds a linear relationship. This temperature viscosity relationship is the base of the auto lubricant technology. Viscosity and density are two different physical phenomena depending on totally different aspects. The common misconception of "heavier fluids are more viscos" is to be omitted. ( Full Answer )
There is no difference in viscosity. A 10w30 full synthetic is the same as a 10w30 blend.
Because liquids with a high viscosity flow slowly as to where aliquid with a low viscosity flow quickly
fluidity is that how easily a liquid flows and viscosity is how rigid era the particles of the liquid are
Obviously 100% viscose is made wholly of viscose - while 50/50 is a mix of equal proportions of cotton and viscose !
transparancy is how much light can get through something, and viscosity has to do with thickness of a liquid
Not really. You may have some change if you mix them but nothing you could really measure. The viscosity is a product of the base oil used and the additive package used by the manufacturer. While heavier oils tend to have a higher viscosity they also suspend more dirt and ash as they are being pumpe…d through the system. Because of this they can cause the heat to fluctuate inside an engine and also affect fuel economy. For almost all applications on modern automobiles the oil you purchase across the counter is more than effective enough to provide engine or any other gear box protection. ( Full Answer )
No. There is no relation between refractive index and viscosity asviscosity is just the flow of electrons. Instead, refractive indexwould be dependent on density
There are several methods. Most use the time it takes, for a standard measured volume to pass through a small hole. It takes the form of a viscosity cup, which holds the required amount and has the standard sized hole at the bottom. Seal the hole with your finger, pour liquid in upto the mark, l…et go your finger at the same time as starting a stopwatch. Stop the watch when the stream first breaks. Viscosity is measured in seconds (redwood scale) ( Full Answer )
The more viscous the liquid (higher the viscosity), the more time it takes to flow through a hole, given a the same pressure difference.
What is the difference between low gas low viscosity eruptions compared to a height viscosity and high gas eruptions?
Low gas and low viscosity versus high gas and high viscosity eruptions are characterized by completely different types of eruption. The low gas and low viscosity eruption would be a Hawaiian type of eruption, were the lava free flows from the ground down slope often at the pace of a brisk walk. The… lava flows are very hot and destructive, however donot normally result in loss of life, as the flows are rather slow moving and non-explosive. The type of magma that would cause this type of eruption is basalt, and would create a mountain similar to Mauna Loa and Kilauea on the big island of Hawaii. A high gas and high visocisty eruption would often times be very explosive as the gasses inside the volcano would be trapped until the pressure would be enough to overcome the force of the volcano holding it inside. This would often times result in a highly explosive eruption as the minute that gas would be released the dissolved gasses inside the magma would begin to fall out of solution and create large bubbles raising the pressure even further in the magma chamber. The type of magma that would cause these high power eruptions would be Rhyolite. Rhyolite is very resistant to flow and readily traps gasses within it in the process. Examples of volcanoes that produce these types of eruptions would be Krakatau in Indonesia, as well as Mt. St. Helens in Washington. ( Full Answer )
Viscosity is a measure of resistance to flow in a fluid. A volcanic eruption is a violent discharge of molten rock and ash.
Viscostity is the thickness of a fluid and hardness is of a solid. for example, u would b measuring the viscosity level difference between ketchup and water. water is thin and it's flow rate is fast but ketchup has high viscosity so it's flow rate is slow -zainab
Higher the viscosity then velocity gradient would be higher. Velocity gradient is the ratio of change of velocity to the distance between the layers of the liquid
The LOWER the Viscosity of a Fluid is, the easier it is to Compress. Keep in mind that Fluids include Gases and Liquids. However, Liquids are NOT Compressible .
THE DIFFERENCE IS THAT OF VISCOSITY .... HPMC K15M (15 cps) HPMC K100M (100000 cps )
Viscosity is how slowly a fluid will move or pour at specified temperature. Specific Gravity is how heavy it is in relation to its volume.
The term HPMC can be HydroxyPropyl MethylCellulose is a science term. It is is the category of chemistry. It is a a synthentic compound that is used in eye and oral medications.
