17 Dec 2011 Water and gasoline are thin liquids while motor oil is thicker. Corn syrup and molasses are even thicker and the thickness of a liquid is related to Our density & viscosity measurement devices offer unbeatable performance for applications in alcohol concentration, API gravity, specific gravity and more. The difficulty of making viscosity and specific gravity determinations on the oil in Athabasca bituminous sand is that there is no method available for getting the 27 Mar 2016 Crude oil properties are important for us to understand what they mean and of crude oil are specific gravity or API gravity, viscosity, color, and odor. As such, we measure the weight of water versus the weight of crude oil.

Heavy oil typically has a viscosity of 100 centipoise or greater. Extra heavy oil is Heavy crude oil is any liquid petroleum with an API gravity of less than 22.3°. Some correlations are known to predict the viscosity of dead-oil as function of API gravity and temperature, (Beal,  2 Jun 2015 definition of heavy crude oil is crude oil with API gravity less than 20, according to the starting point for live oil viscosity and density predic- tions. where P is the pressure, T is the temperature, v is the molar volume, Rg is These are American Petroleum Institute (API) gravity and viscosity, wax content, WAT and Viscosity of Dulang crude oil vs. shear rate at different temperatures The viscosity of crude oils can be measured using a standard method (ASTM D2983).

Oil viscosity. Absolute viscosity provides a measure of a fluid’s internal resistance to flow. For liquids, viscosity corresponds to the informal notion of "thickness". For example, honey has a higher viscosity than water. Any calculation involving the movement of fluids requires a value of viscosity. Crude oil's viscosity can vary from a low-viscosity liquid to up to tar-like, nearly solid form. Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³) Medium crude oil: API gravity from 31.1 °API to 22.3 °API (870 to 920 kg/m³) *Centipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120). Oil viscosity is the parameter that plays an important role in lubrication. It changes with temperature, shear rate, pressure, and thickness. Oil viscosity is graded by measuring the time it takes for a standard amount of oil to flow. Motor oil viscosity is a common term we need to understand completely, and it refers to An increase in the temperature usually reduces the viscosity; conversely, a temperature reduction usually increases the viscosity. Pipe friction loss increases as viscosity increases. Specific Gravity - Direct ratio of any liquid's weight to the weight of water at 62 degrees F. Water at 62 degrees F weighs 8.33 pounds per gallon and is designated 1.0 sp. gr. The viscosity at 35°C was about 10-to 15-fold of the viscosity at 180°C. This will have significant effects on the energy required to pump the oil and on the rate of heat transfer at elevated temperatures. In addition, the viscosity values obtained in this study were within 12% of the viscosity values reported in literature for soybean, corn
The numbers after the “XW” indicate viscosity at 100 degrees Celsius and represent the oil’s resistance to thinning at high temperatures. For instance, oil with a 5W-30 grade thickens less than oil with a 10W-30 grade in cold weather. Oil with a 5W-30 grade thins out more quickly at high temperatures as compared to oils with a 5W-40 grade.

the physical properties of oil such as density, viscosity and surface tension which can in turn affect the transport rate of oil, and thus the rate of oil absorption. Hence, the focus of this study is to understand the change in the oil physical properties at high temperatures, to better predict the effect
