Similarly, the specific gravity of aggregate is required to be considered when we deal with lightweight and heavy-weight concrete. It is used to calculate specific gravity of cement instead of water. Urine specific gravity is a measure of urine concentration. URI carries National Refrigerants and more. Specific gravity values aren't very useful except for predicting whether or not something will float on water and for comparing whether one material is more or less dense than another. Optimal Result: 1.005 - 1.03 SG. Water has a liquid density of 62.42 pounds per It is compatible with POE synthetic oils.
