What is the viscosity of juice?
The viscosity data of juices (1.53–3300 mPa s) were obtained from the literature for a wide range of concentration (5–70 °Brix) and temperature (30.7–71.7 °C).
Do liquids have high viscosity?
Fluids with low viscosity have a low resistance and shear easily and the molecules flow quickly; high viscosity fluids move sluggishly and resist deformation. Some liquids, like pitch, glass and peanut butter, have such high viscosity they behave like solids. Viscosity varies with temperature and pressure.
What fluids have a high viscosity?
Liquids which flow very slowly, like glycerin or honey, have high viscosities. Those like ether or gasoline which flow very readily have low viscosities. Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid.
Does orange juice have a high viscosity?
The viscosity of the clarified juice was appreciably lower than that of regular juice, i.e. 15.55 mPa for serum and 164 mPa (at 100 s−1) for regular orange juice concentrate (65 °C, 66.5 ∘Brix). Flow behavior of orange juice serum tended to be Newtonian.
What is the viscosity of honey?
| Approximate Viscosities of Common Materials (At Room Temperature-70°F) * | |
|---|---|
| Material | Viscosity in Centipoise |
| Castrol Oil | 1,000 cps |
| Karo Syrup | 5,000 cps |
| Honey | 10,000 cps |
Does orange juice have a higher or lower viscosity than chocolate syrup?
Answer: Orange juice has a lower viscosity than chocolate syrup.
Why does maple syrup have a higher viscosity than orange juice?
The Molecules that make up maple syrup have a harder time moving past one another because they are larger than the molecules that make up orange juice. The molecules that make up maple syrup have a harder time moving past one another because they are smaller than the molecules that make up orange juice.
How viscosity is related to the flow and attraction between atoms in a liquid?
Viscosity is also known as fluid friction is the contact force that exists between the atoms. The atoms of liquid upon contact experience a strong force of attraction. Due to this attraction, the atoms of liquid resist the flow of motion. The higher the resistance is shown by a liquid, the higher will be its viscosity.
What are some liquids with low viscosity?
Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
What is the measure of viscosity?
The fundamental unit of viscosity measurement is the poise. A material requiring a shear stress of one dyne per square centimeter to produce a shear rate of one reciprocal second has a viscosity of one poise, or 100 centipoise.
What is viscosity explain with example?
If I fill the same cup with water, for example, the cup will drain much more quickly. Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction.
What is the use of kinematic viscosity?
Kinematic viscosity is a measure of a fluid’s internal resistance to flow under gravitational forces. It is determined by measuring the time in seconds, required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely controlled temperature.
Is higher or lower kinematic viscosity better?
The higher the kinematic viscosity, the more a fluid is able to transport momentum. Highly viscous fluids and liquids of low density are good candidates for excellent momentum transport properties. In water it takes about 10 ms for momentum to diffuse over a length of l = 100 µ m.
What is kinematic viscosity equal to?
The kinematic viscosity is equal to the ratio of the dynamic viscosity by the density. The kinematic viscosity is involved in the classical Navier Stokes equation governing the fluid motion.
How can you express kinematic viscosity?
Kinematic Viscosity
- 1 St = 100 cSt.
- 1 cSt (centiStoke) = 10-6 m2/s = 1 mm2/s.
- 1 m2/s = 106 centiStokes.
