Specific gravity = 705 divided by 62.4 = 11.3 specific gravity OK? My method: The weight of the specimen in water is pulling on the string less because a portion of the weight is pushing down on the scale as you suspend the mineral. In my method the same example of lead results in these measurements: Dry weight (DW): 705 grams

MoreMar 19, 2017 To determine each minerals specific gravity, a standard to measure each against was needed. The standard that was chosen was the weight of water. To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of water. Weigh the water that was displaced by the mineral.

MoreThe ground barite also must be dense enough so that its specific gravity is 4.2 or greater, soft enough to not damage the bearings of a tricone drill bit, chemically inert, and containing no more than 250 milligrams per kilogram of soluble alkaline salts.

MoreJan 06, 2021 The density of any material is derived by multiplying the specific gravity of that material by the density of pure water. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water.

MoreS.G. is defined as the weight of a body compared with the weight of an equal volume of pure water. The specific gravity of a gemstone is a ratio which could be of great help in identifying gemstones. Although a gemstone cannot normally be identified by its S.G. alone, together with other measurements this can help in narrowing down the range of possibilities.

MoreDec 13, 2016 Specific gravity (also known as "relative density") is the ratio between the weight of a stone in air and the weight of an equal volume in water. By convention, the temperature of the water is 4° C and at standard atmosphere because the density of water is greatest under these conditions.

MoreI measure specific gravity by the same way, with a few slight changes. I boil the water and allow it to cool before using it. This eliminates dissolved air, which prevents bubble formation. Instead of using thread to tie the sample I use very thin copper wire, which

MoreApr 24, 2017 Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure. To calculate the rock density

MoreThe specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water.

MoreWater has a density of 1.0 g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific gravity is easier to measure than density. In order to measure specific gravity you

MoreSome measurement precautions are necessary to obtain the best results from this procedure. They are as follows: 1. The graph in Figure 3 and formulas are for rock that has a specific gravity of 2.65 (165 pounds per cubic foot). Use this graph or formula unless the actual specific gravity (Gsa) is

MoreSpecific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is the measure of strength or quality of the specific material. Aggregates having low specific gravity are generally weaker than those with higher specific gravity values.

MoreJan 01, 2001 Barite. Barite (BaSo 4) is a widespread naturally occurring high gravity mineral with a specific gravity ranging from 4.2 to 4.6 and a hardness index of 3.0.It is a non-reactive solid used to increase mud weight up to 22 ppg. Barite was formed under low to moderate temperatures in hydrothermal veins.

MoreFeb 20, 2015 Barite is by far the most common weighting material used in drilling fluids. It has an API defined specific gravity of 4.2, which makes it possible to increase mud weight up to 21 ppg. It is cheap and readily available. However, suspension of barite requires high gel strength and viscosity. Hematite is sometimes used depending on the availability.

MoreApr 08, 2019 This makes specific gravity a unitless measurement. Use the ratio "W l / W water ” where W l is the weight of your liquid and W water is the weight of water. For example, if you weighed 100 mL of acetone at 25 degrees Celsius, it would weigh 0.17314 pounds. Weighing the same volume of water at the same temperature would give you 0.22 pounds.

MoreBarite (spelled baryte in British publications) was named from the Greek word baros which means weighty, a reference to its unusually high specific gravity. (Specific gravity is a mineralogist’s measure of the density of a mineral; this is done by comparing the weight of the mineral to the weight of an equal volume of water.)
