In equation form: SG = /w. Some values are approximate. gal. Once you know density, you calculate specific gravity (SG) by dividing the density of the object by the density of water (w). theForm.strength.focus(); These cookies track visitors across websites and collect information to provide customized ads. decPoints++; Specific Gravity of Liquid 1 is the specific gravity of the below liquid. In equation form: SG = /w. { return (false); Easy Calculation. If the petroleum product is lighter than water, it will float and its API Gravity will be more than 10. theForm.strength.focus(); Learn how to use the Gardco Weight Per Gallon Cups. 345 lbs/U. United States Geological Survey: Water Density, The Engineering Toolbox: Density, Specific Weight and Specific Gravity, Science Notes: How Much Does a Gallon of Water Weigh? Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. Although the two terms often are used interchangeably, there is a technical difference between specific gravity and density. Pure RO/DI water without any salt should measure 1.000 Specific Gravity. Since weight is a force, scientists also write the equation as F = mg.F = symbol for weight, measured in Newtons, N.m = symbol for mass, measured in kilograms, or kg.g = symbol for gravitational acceleration, expressed as m/s2, or meters per second squared. If you're using meters, the gravitational acceleration at the earth's surface is 9.8 m/s 2. Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. break; return (false); Pipe friction loss increases as viscosity increases. else if (window.attachEvent) var checkOK = "0123456789-.,"; theForm.specgrav.focus(); if (ch == ".") { alert("Please enter only digit characters in the \"chemlbs\" field. if (decPoints > 1) "); Thus, the volume in pounds is equal to the gallons multiplied by 8.345404 times the density of the ingredient or material. ch = checkStr.charAt(i); Your email address will not be published. Webmass = d v vcfmcf, where mcf is the conversion factor to convert from pound to kilogram (table near the end of this page) and vcf is the conversion factor to convert from US gallon to cubic meters. The density was measured at 30C (86F or 303.15K) at standard atmospheric pressure. of water)),
