Question 7

Pick out the wrong statement.

Accepted Answer

Heavier petrofuels have higher GCV on weight basis (i.e., Kcal/kg) but lower GCV on volume basis (i.e., Kcal/litre)

Answer

Aromatics have higher specific gravity than paraffins

Answer

Gross calorific value (GCV) of petrofuels is equal to (12400 - 2100 ρ 2 ) where, ρ is the specific gravity of the fuel at 15.5°C

Answer

Higher specific gravity of petrofuels means higher C/H ratio
