Glycol any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol two hydroxyl groups are attached to different carbon atoms. The term is often applied to the simplest member of the class ethylene glycol. Learn more about glycols in this article.
PEG 400 - Wikipedia
PEG 400 polyethylene glycol 400 is a low-molecular-weight grade of polyethylene glycol. It is a clear colorless viscous liquid. Due in part to its low toxicity PEG 400 is widely used in a variety of pharmaceutical formulations. Chemical properties. PEG 400 is strongly hydrophilic.
Specific Gravity of Fermentables Homebrew Exchange
The PPG is the specific gravity you would get if you dissolved or mashed one pound of the ingredient in one gallon of water. For example if the PPG of liquid light malt extract is 1.036 then putting 5 pounds in 5 gallons of water 1 lb/gal would yield a gravity of 1.036.
Specific Gravity Of General Materials Table
As specific gravity is just a comparison it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft pounds per cubic foot and if we know that a sample of ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.
Ethylene Glycol Heat-Transfer Fluid
The density of ethylene glycol is higher than water - check the specific gravity SG table above so the net impact on the heat transport capacity is reduced. Example - the specific heat of an ethylene glycol water solution 50% / 50% is 0.815 at 80 o F 26.7 o C . Specific gravity at the same conditions is 1.077.

Viscosity Tables - V and P Scientific
Viscosity Tables : Viscosity is the measurement of a fluid& 39;s internal resistance to flow. This is typically designated in units of centipoise or poise but can be expressed in other acceptable measurements as well. Some conversion factors are as follows: 100 Centipoise = 1 Poise 1 Centipoise = 1 mPa s Millipascal Second

The table below provides specific gravity ratings for common fluids. As you review the specs for our different float switches not the specific gravity rating. To achieve bouyancy the specific gravity of the float must be lower than the specific gravity of the fluid being measured. Water is the benchmark with a specific gravity of 1.0.

Difference Between Density and Specific Gravity
However because the density of pure water is so close to 1 0.9976 grams per cubic centimeter specific gravity and density are nearly the same value so long as the density is given in g/cc. Density is very slightly less than specific gravity.
Specific Gravity Chart - Gemstone Information - GemSelect
Specific gravity is an important tool in gemstone identifi ion that is useful for the gem buyer as well as the gemologist. A 1-carat stone with higher specific gravity will be smaller than a 1-carat stone with lower specific gravity. So don& 39;t be surprised when the sapphire you buy is smaller than your diamond. That& 39;s because sapphire has a

A Guide to Glycols
Specific Physical Properties Freezing Point When liquids are cooled they eventually either crystallize like ice or become increasingly viscous until they fail to flow and set up like glass. The first type of behavior represents true freezing. The second is known as super-cooling. Glycols do not have sharp freezing points.
Which to Use: Ethylene or Propylene Glycol? 2017-08-01
Table 2 compares the viscosity of both ethylene glycol and propylene glycol. Specific gravity is a referenced physical property when working with glycol solutions. With a direct relationship to density it is important to consider data on specific gravity in the calculation of a number of engineering expressions.
