Fluid Properties Viscosity #2

In the absence of any laboratory data, correlations exist that relate viscosity  and temperature, given the oil gravity. The following equation  relating viscosity, gravity, and temperature was developed by Beggs and  Robinson after observing 460 oil systems: The data set … Continue reading

Fluid Properties Viscosity #1

This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid is in motion. Viscosity, therefore, is simply the ratio at any shear rate of the … Continue reading

Specific Gravity and Density

Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is related to the specific gravity by the following equation: The specific gravity of a gas … Continue reading
