Liquids - Kinematic Viscosities - The Engineering ToolBox
2012年11月4日 · Kinematic viscosities of some common liquids like motor oil, diesel fuel, peanut oil and many more. Viscosity is resistance to shear or flow in a fluid - and a measure of the adhesive/cohesive or frictional property.
Mineral oil - Wikipedia
More generally, mineral oil is a transparent, colorless oil, composed mainly of alkanes [2] and cycloalkanes, related to petroleum jelly. It has a density of around 0.8–0.87 g/cm 3 (0.029–0.031 lb/cu in).
Oil viscosity - PetroWiki
2015年6月4日 · 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.
Mineral Oil Base Fluids - SpringerLink
Some of the key mineral oil properties include (a) viscosity, (b) oxidative stability, (c) volatility, (d) solvency, (e) pressure-viscosity coefficient, (f) pour point, and (g) color. Viscosity is the single most critical mineral oil property.
Mineral Oil - an overview | ScienceDirect Topics
There are, broadly speaking, two types of mineral oil: paraffinic, having comparatively long alkyl side chains in the molecule and consequently high KVI, together with a ‘wax’ pour point; and naphthenic, having comparatively short side chains, low to medium VI and a ‘viscosity’ pour point.
MINERAL OIL (MEDIUM VISCOSITY) Add 10 (2002) and republished in FAO JECFA Monographs 1 (2005). An ADI of 0-10 mg/kg bw was establishe. At the 76th JECFA the temporary ADI and the specifications for mineral oils (Medium and low viscosity), class II and class III were withdrawn. IDENTIFICATION. Solubility (Vol. 4)

In terms of the viscosity index, the worst mineral oils known at the time were awarded a VI of 0, and the mineral oils with the best viscosity-temperature behaviour were awarded a VI of 100. At the time, there were no synthetic or multigrade oils.
Oil Viscosity: A Practical Guide - Precision Lubrication
Oil viscosity is the internal friction within an oil that resists its flow. It measures the oil’s resistance to flow and is one of the most important factors in lubricants. Viscosity is also defined as the ratio of shear stress (pressure) to shear rate (flow rate).
