relative density/specific gravity
Плотность гидравлических масел – это масса единицы жидкости. Этот показатель имеет прямую зависимость от температурных характеристик и давления, т.к. при увеличении температуры увеличивается и объём масла.

What temperature is best to measure the relative density of a lubricant in order to calculate its volume?”
Density plays a critical role in how a lubricant functions as well as how machines perform. Most systems are designed to pump a fluid of a specific density, so as the density begins to change, the efficiency of the pump begins to change as well.
The ASTM D1298-12b Standard Test Method for Density, Relative Density, or API (American Petroleum Institute) Gravity of Crude Petroleum and Liquid Petroleum Products states that accurate determination of the API gravity, density or relative density (specific gravity) uses a standard temperature of 60 degrees F (15 degrees C).
In Layman’s terms, density is the mass of an object relative to the volume it occupies. Mathematically, density, mass and volume are related according to the following formula:
ρ=m/V where ρ=density, m=mass and V=volume.
The density of most oils will range between 700 and 950 kilograms per cubic meter (kg/m3). By definition, water has a density of 1,000 kg/m3. What this means is that most oils will float on water as they are lighter by volume. This is not always the case, as some Group IV base oils can have a higher density than that of water, effectively causing the oil to sink in the water.
The API measurement of density is reported a little differently. This measurement uses a comparison to water on an inverse scale. Water is represented by a 10 on the scale. Anything greater than 10 has a lower density than the water and will float upon it. Anything less than 10 will be heavier and sink in the water. Below is a chart displaying how API relates to specific gravity and weight per volume/

: A long-winded meaninglless answer to a simple question. You like to hear yourself. We're talking about steam not oil. A PhD = BS-Bull $hit; MS-More $hit; PhD-Piled higher and Deeper. Get real.
