Jun 26 2015The Specific Gravity (SG) of a substance is a measure of its density It is expressed as the ratio of the weight of a given volume of the substance compared to the weight of an equal volume of a reference substance – usually water An alternative term sometimes used is

Both density and specific gravity describe mass and may be used to compare different substances They are not however identical measures Specific gravity is an expression of density in relation to the density of a standard or reference (usually water)

This procedure covers the determination of specific gravity and absorption of coarse aggregate in accordance with AASHTO T 85-10 Specific gravity may be expressed as bulk specific gravity (Gsb) bulk specific gravity saturated surface dry (Gsb SSD) or apparent specific gravity (Gsa)

Abstract These test methods cover the determination of the specific gravity of soil solids passing a sieve by means of a water pycnometer Soil solids for these test methods do not include solids which can be altered by these methods contaminated with a substance that prohibits the use of these methods or are highly organic soil solids such as fibrous matter which floats in water

Jan 11 2018Specific gravity is a concept that shows up in a variety of industrial applications particularly as it relates to fluid dynamics For example if you've ever taken your car in for service and the mechanic showed you how small plastic balls floated in your transmission fluid you've seen specific gravity in action

SPECIFIC GRAVITY DETERMINATION Purpose This lab is performed to determine the specific gravity of soil by using a pycnometer Specific gravity is the ratio of the mass of unit volume of soil at a stated temperature to the mass of the same volume of gas-free distilled

Feb 04 2012Specific gravity or relative density is the ratio of the density of the fluid to the density of water at standard temperature in example at 40C Specific gravity can be determined directly from the density of a liquid as measured divided by standard density of water

The specific gravity of the solid is the ratio of its weight in air to the difference between its weight in air and its weight immersed in water Two methods are commonly used for determining the specific gravities of liquids One method uses the hydrometer an instrument that gives a

Specific Gravity Determination There is a quick and easy method of determining the density or sp g of a liquid based upon the fact that a floating body is buoyed up more by a heavy liquid than by a light one The method is more remarkable for speed than accuracy but still is sufficiently exact

Purpose of test To determine the specific gravity of soil fraction passing 4 75 mm sieve by pycnometer Use of specific gravity value The knowledge of specific gravity is needed in calculation of soil properties like void ratio degree of saturation etc

You can determine the specific gravity of a body a second method using just a balance and graduated cylinder to determine the specific gravity hydrostatically This method is best used for larger samples 1 Weigh specimen in grams 2 Partly fill a graduated cylinder (cc)

Specific gravity ratio of the density of a substance to that of a standard substance The usual standard of comparison for solids and liquids is water at 4 C (39 2 F) which has a density of 1 0 kg per litre (62 4 pounds per cubic foot) Gases are commonly compared with dry air which has a

In order to promote public education and public safety equal justice for all a better informed citizenry the rule of law world trade and world peace this legal document is hereby made available on a noncommercial basis as it is the right of all humans to know and speak the laws that govern them

Determination of Specific Gravity of Soil Lecture Note 2– (Thursday 01-29-04) 1 Definitions Objectives and Applications (class notes) 2 Equipment 1 Volumetric flask (500 ml) with stopper having pipe hole 2 Thermometer graduated in 0 5oC division scale 3 Balance sensitive to 0 01 g 4

Gravity in the context of fermenting alcoholic beverages refers to the specific gravity or relative density compared to water of the wort or must at various stages in the fermentation The concept is used in the brewing and wine-making industries Specific gravity is measured by a hydrometer refractometer pycnometer or oscillating U-tube electronic meter

Unless otherwise stated in the individual monograph the specific gravity determination is applicable only to liquids and unless otherwise stated is based on the ratio of the weight of a liquid USP29 in air at 25 to that of an equal volume of water at the same temperature Where a temperature is specified in the individual monograph the specific gravity is the ratio of the weight of the

This lab is performed to determine the specific gravity of soil by using a Pycnometer or Specific Gravity Flask Specific gravity is the ratio of the mass of a unit volume of soil at a stated temperature to the mass of the same volume of gas-free distilled water at a stated temperature Procedure 1

determination of density and specific gravity of a liquid The operation of the hydrometer is based on the Archimedes principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced Thus the lighter the liquid (that is the less its specific gravity

Alcohol Determination By Specific Gravity -This method provides an approximation of the alcohol content only The method assumes that the difference in Specific Gravity before and after fermentation is due solely to the conversion of sugars before fermentation into alcohol after fermentation

In the aggregates some of the pores are permeable whereas others are impermeable Therefore two types of specific gravities are defined one is the absolute specific gravity and second is the apparent specific gravity In the determination of true or absolute specific gravity both the permeable and impermeable voids are excluded

Specific gravity measurements are a way to relate the density of a given substance to the density of water This is mainly owing to the universal nature of water Note that the density of water varies slightly with temperature so specific gravity is also a temperature-specific unit How to Determine Specific Gravity
