Sunflower oil, high oleic: Refined: 232 °C: 450 °F [3] Sunflower oil, high oleic: Unrefined: 160 °C: 320 °F [3] Vegetable oil blend: Refined: 220 °C [13] 428 °F
Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of edible plants. Like animal fats, vegetable fats are mixtures of triglycerides. [1] Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of ...
A number of oils are used for biofuel (biodiesel and Straight Vegetable Oil) in addition to having other uses. Other oils are used only as biofuel. [note 4] [147] Although diesel engines were invented, in part, with vegetable oil in mind, [148] diesel fuel is almost exclusively petroleum-based. Vegetable oils are evaluated for use as a biofuel ...
where U is the oil's kinematic viscosity at 40 °C (104 °F), Y is the oil's kinematic viscosity at 100 °C (212 °F), and L and H are the viscosities at 40 °C for two hypothetical oils of VI 0 and 100 respectively, having the same viscosity at 100 °C as the oil whose VI we are trying to determine.
Tests such as viscosity, specific gravity, flash point, fire point, pour point, acid number, and saponification number were devised to distinguish between petroleum and animal/vegetable oils. Of these, while some such as viscosity were relevant to selecting the right oil for an application, most were useful only for detecting adulteration.
Extensional viscosity can be measured with various rheometers that apply extensional stress. Volume viscosity can be measured with an acoustic rheometer. Apparent viscosity is a calculation derived from tests performed on drilling fluid used in oil or gas well development. These calculations and tests help engineers develop and maintain the ...
