Saturated Gas. How to Determine Specific Gravities of Alloys. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity … Saturated Liquid. The formula for the density of water based on temperature is: ρ = ρH2O 1+ β(T −T 0) ρ = ρ H 2 O 1 + β ( T - T 0) where: ρ is the density of water at a specific temperature. But rather than explicitly listing the specific units associated with a particular density (e.g., grams per cubic centimeter, pounds per cubic inch), specific gravity allows us to simplify by dividing by the specific gravity of water, which is the density of water at 4 degrees Celsius. Specific gravity is density compared to density of water (For gases, it is often compared to the density of air). (15.56o/15.56o C.). The calculator supports Plato and SG for inputs and reports apparent attenuation, calories, and the OG/FG in both sugar scales. Measurement: Scale : Temperature: Scale: Original: Final : Categories. The temperatures are usually the same and value of 60 O F/60 O F (15.6 O C/15.6 O C) is commonly used. Knowing the specific gravity of the natural gas, calculate the pseudocritical temperature and pressure by applying Eqs. The true specific gravity of a material can be determined at the specific temperature to the true density of water. Oil gravity differs for each liquid. In order to make full use of your hydrometer the first thing that you need to know Specific gravity (sp gr) measures the ratio of density of the substance to the density of water in a given temperature, (i.e., 4 o C). 6. Using the calculator below, enter the temperature of the sample and the observed standard gravity reading to obtain the corrected standard gravity (SG). Specific gravity (or relative density) is a relative measure of density and is ratio between the density of fluid at a specified temperature to the water density at some standard temperature. The temperature of the test: 23 ºC.
