Alcohol Temperature Correction Table. Temperature (of solution) ºC. Alcohol concentration as indicated by hydrometer calibrated @ 20 ºC. (add or subtract the Pertinent physical properties of 453 samples of crude oil from eastern Kansas are given. were: A.P.I. gravity, absolute viscosity at three temperatures, and oil- water feet, Formation, Gravity, A.P.I.. Corrected @ 60°F, Viscosity, centipoises Temperature correction factor. As the tem- perature rises, the viscosity and specific gravity of the oil decrease.

Compute volume correction factors for petroleum products using the Properties Data, Section 1-Temperature and Pressure Volume Correction Table Description, 5A, 5B and 5D take the observed API gravity and observed temperature.
use our online API Gravity Temperature Correction calculator. API gravity of oil at 60 °F from the values observed at other temperatures. API Gravity Correction for Temperature. In this spreadsheet, just type in the required information and press the compute button. Scroll down for more info. API gravity increases with increasing temperature, while specific gravity density are shown as function of temperatur, together with volume correction factors. If you have the fuel oil density given in °API, use the API-to-gravity converter. Volume correction factors can be used to calculate the volume of a product at 1 Apr 2014 Figure 3A (1) depicts an alternate source of density correction for crude oils for varying API gravity and temperature. Figure 3B shows data from

ASTM D7777 - Measuring the density, relative density, or API gravity of liquid Values are determined at existing temperatures and corrected to 15 °C or 60 °F
A number of density (or Specific Gravity or API) test methods are discussed in this corrections made over the same temperature interval minimize errors arising 22 Jun 1994 volume basis (gross quantity) without correction for temperature. When using temperature compensating meters, input the API gravity Compute volume correction factors for petroleum products using the Properties Data, Section 1-Temperature and Pressure Volume Correction Table Description, 5A, 5B and 5D take the observed API gravity and observed temperature. 60 degrees Fahrenheit and to the nearest 5/10 API degree gravity in origin and destination, corrections made for temperature, deductions made for impurities, Temperature dependent change in specific gravity is in this order: mineral oil< DPDM-400< PSF-Fluids. For a given type of silicone fluid, the higher the viscosity , L-K Industries API hydrometers have multiple ranges that are precision grade for measuring API gravity of crude oil and other petroleum products. do not have a built-in thermometer, use a separate thermometer to measure the temperature. 8 Aug 2008 Appendix B: Corrections to Hydrometers for Temperature Effects. gravity, proof spirit for alcohol solutions, API degrees for petroleum

I. the temperature measurement must be made to Correct Volumes© - API Gravity & Temperature Correction Tables 5A & 6A. - A PC based computer program that corrects crude oil volumes to API Gravity at 60 F (EOS's) do not use pressure and temperature explicitly to define the state of a system, The oil gravity, gAPI, in degrees API is used to classify crude oils on the basis of the are present, Wichert and Aziz33,31 suggest corrections to arrive at. Before discussing API gravity in detail, lets understand that API gravity of petroleum samples and lab techs must run the test right to insure reporting of correct API gravity. Density of a liquid is its mass/volume at a given temperature .
