Calculate the density of your chosen sphere. The density of both the sphere and the liquid are needed to perform the viscosity calculation. The formula for density is = /, where d is density, m is the mass of the object, and v is the volume of the object.. Measure the mass by placing the sphere on a balance. Record the mass in grams (g).
Depending on your process requirements, you can use various tools to measure viscosity. Here are three: Get easy viscosity measurements at various temperatures using a viscosity cup. Simply pour the test liquid into the cup. The liquid will stream out of the opening on the bottom. Measure the time until the first break in the flow of liquid.
A falling ball viscometer measures the viscosity of fluids and some units can also measure the viscosity of gases. Viscosity cups The various forms of viscosity cups use gravity to allow a fluid to flow through an orifice located at the bottom in a precise amount, which can be measured over time to calculate a viscosity value.
Ways to Measure Viscosity. Way back in the 1800's, the first measurements of viscosity were made using capillary tube methods. The following is a brief summary of the different techniques and instruments that have since been developed, and are in use today.
Viscosity Cups. Viscosity cups are used to determine a fluid’s kinematic viscosity. This relatively simple test involves placing the fluid in a container with a small opening at the bottom. The fluid is allowed to flow through the opening in a precise amount.
The actual times for the liquids will depend on the size of your viscometer and the temperature of your liquids. Your viscosity index for maple syrup should be 150-200 times that of water. Most shampoos have 10-100 times the viscosity of water. Why. Viscosity is caused by friction within the liquid.
Now do the absolute viscosity test by stirring the fluids. The test will show that honey is the more viscous fluid. Perform the kinematic viscosity test by turning the jars on their sides, and the test will show that the mayonnaise is now the more viscous fluid (the honey flows out faster than the mayonnaise).
There are many techniques for measuring viscosity, including flow rate through an orifice, rate of a descent of a weight through the fluid, and torque required to rotate a spindle in the fluid (see, for instance, Brookfield viscometer). The viscos...
Viscosity is an important aspect for oil used in machines and transportation vehicles. Viscosity is defined as how the oil flows as a result of gravity. Viscous fluids help lubricate machines as their internal parts move. In the case of motor vehicle engines, viscous oil helps lubricate engine parts from overheating ...
Different ways of measuring viscosity includes capillary viscometers, rotational viscometer, falling sphere viscometer, Zahn Cup method, vibrational viscometer, and VROC technology. Incorporating MEMS & microfluidic technologies, viscosity can be easily measured with precision and simplicity.
