This app provides volume and/or densities changes calculations due to temperature and pressure changes. Calculations are for Crude Oil, Refined Products, Lube Oils, and Specialized products. Refined Products include gasolines, alkylate, naphtha, jet fuel, kerosene, diesel. Minimum data requirements are: Density (API, S.G. or kg/m3), temperature (°F) at which density was measured and pressure (PSI). A volume is not required, but if entered, the corrected volume will be calculated. The volume measurement conditions need be indicated: either at (1) the density temperature and pressure or (2) at the Alternate temperature and pressure. Volume units of measure are not required. The latest case performed is saved and can be recalled from memory. Base conditions are 60°F and 0 PSI . Based on API published correlations.
