Specific gravity of a petroleum product gives an indication of its A. degree of refinement. B. hydrocarbon content type (aromatic or paraffinic). C. ease of atomisation. D. sulphur content.
Pick out the wrong statement. A. Aromatics have higher specific gravity than paraffins, B. Gross calorific value (GCV) of petrofuels is equal to (12400 - 2100 ρ2) where, ρ is the specific gravity of the fuel at 15.5°C. C. Heavier petrofuels have higher GCV on weight basis (i.e., Kcal/kg) but lower GCV on volume basis (i.e., Kcal/litre). D. Higher specific gravity of petrofuels means higher C/H ratio.
