How is castor oil viscous?
They found COB’s viscosity value as 13.75 mm2. s-1 (at 40°C), sulphur value as 0.0001%, density as 0.9279 g.
What is the viscosity of castor oil in centipoise at 20 degree Celcius *?
Approximate Viscosities of Some Common Liquids
|Liquid||Specific Gravity @ 16°C||Absolute Viscosity cP|
|Carob Bean Sauce||1500|
What is the value of viscosity of oil?
Crude oils – viscosity and °API
|Crude Oil||Kin. Viscosity [mm²/s] at Temp.||API Gravity °API|
|Arabian Light||10.7 at 20 °C||34.2|
|Bonny Light||2.90 at 50 °C||35.4 35.8|
|Boscan||11233 at 100 °F||10.1|
|Brent||2.86 at 50 °C||37.9 38.2|
Which is more viscous water or castor oil?
More thick a liquid is, more slowly it will flow’. There is no relationship between viscosity and density of a fluid. But oil is more viscous than water and thus when when we put a drop of water and oil on a slant surface, water will move downwards more quickly than the oil drop.
Which has highest viscosity?
Solids have high viscosity because they cannot flow freely. Viscosity of liquids ranges from low to high whereas gases have a low viscosity. Hence, wood being a solid has a very high viscosity.
What increases viscosity?
Viscosity generally increases as the temperature decreases. The viscosity of a liquid is related to the ease with which the molecules can move with respect to one another. Thus the viscosity of a liquid depends on the: strength of attractive forces between molecules, which depend on their composition, size, and shape.
What are examples of low viscosity?
Water, gasoline, and other liquids that flow freely have a low viscosity.
What is considered a low viscosity?
Motor oil viscosity is the measure of its resistance to flow. Low-viscosity oil (e.g. 0W-20) flows faster than high-viscosity oil (e.g. 20W-50). To illustrate, think of water and honey. When poured from a container, water flows much faster than honey.
What liquid has the same viscosity as blood?
The fluid found inside the hollow coconut chamber, the coconut water, is a surprisingly good substitute, as it’s nearly identical to human blood plasma: it’s nutritive, sterile, and contains various minerals and amino acids.
