Notice that Oil A, a mineral oil, and oil B, a synthetic PAO oil, have the same viscosity at 40 o C, and would therefore be sold as the same oil. Color: >+30 Saybolt Color units - measured via ASTM D 156. Viscosity is an important physical property of mineral oil, which has an effect on both the electrical and the thermal performance of mineral oil. 2. s/m 2. Previously the viscosity was given in poises (or centipoises, 1 cP = 1 mPas). Low Viscosity Mineral Oil, 4.5 cSt, 1 Liter each. examined and properties such as viscosity, pressure-viscosity coefficient, compressibility and shear strength coefficient of oil and refrigerant mixtures are measured. The last mentioned three characteristics are interdependent. The calculation method described in ISO 2909 was developed approximately 60 years ago. In addition to these three properties, the oil must meet thefollowing specification: 1. Crude oil viscosity as function of gravity - Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F Dynamic or Absolute Viscosity Converting Chart - Dynamic viscosity converting chart with units like Poiseuille - Poise - centiPoise and more It is defined as the internal frictional resistance of a liquid to the application of a pressure or a shearing stress. For oils with the same specific gravity, we would opt for the lower viscosity. The dynamic viscosity h (Greek letter eta) is normally given in millipascal-seconds (mPas) and is usually determined by using a rotary viscometer. The viscosity index (VI), which is calculated with the aid of kinematic viscosity measured at 40°C and 100°C, is used to describe an oil’s viscosity-temperature behaviour. Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils.. Paragon ISO/IEC 17025 and ISO 17034 (ISO Guide 34) certified mineral oil rotational viscosity standards are specifically formulated for use with rotational viscometers. This is typically designated in units of centipoise or poise but can be expressed in other acceptable measurements as well. Includes Newtonian and Thixotropic liquids Density: Specific gravity between .76 and .87 - measured via ASTM D 4052 or ASTM D 1298. The general conclusion of the thesis is that the refrigerant affects all of the measured properties negatively on the subject of lubrication and life of the rolling element bearing. This parameter allows the viscosity behaviour of various oils to be better compared based on temperature. Check the cross-reference charts of Sonneborn products like white oils, plastic oils, PVC oils, and Microcrystalline Waxes to know their typical properties. The name mineral oil by itself is imprecise, having been used for many specific oils over the past few centuries. 3. Actual sulfur value reported in mg/kg examined and properties such as viscosity, pressure-viscosity coefficient, compressibility and shear strength coefficient of oil and refrigerant mixtures are measured. A guide to the approximate viscosities of some common liquids at various temperatures. This is a paraffinic mineral oil, VGC 0.790-0.819, with a viscosity between 12 and 30 cST at 37°C (66-150 SUS), a boiling range of 370-420°C and a mean molecular weight of 340-380. The ideal oil would have a specific gravity in the upper portion (>.83) of the range specified under "required properties" and a viscosity between 12 cST at 40 o C (70 SUS at 100 o F) and 18 cSt at 40 o C (100 SUS at 100 o F). Viscosity: < 34.5 cSt at 40o C (< 172 SUS at 100o F) - measured via ASTM D 445. The general conclusion of the thesis is that the refrigerant affects all of the measured properties negatively on the subject of lubrication and life of the rolling element bearing. The oil must be certified by the manufacturer to have the following properties: 1. Crude oil viscosity as function of gravity - Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F Drag Coefficient - The drag coefficient of an object in a moving fluid influence drag force For example, the dynamic viscosity of water at 20°C … Notice, though the massive increase in viscosity for the mineral oil at -20 o C, and the larger decrease in viscosity at 100 o C. These are two characteristics best avoided in a lubricating oil. Viscosity tests were performed with a rheology meter.
