Fuel Oil Characteristics - continued.
C. Specific Gravity
Specific gravity is the ratio between the weight of a given volume of oil at 60 deg F and weight of an equal volume of water at 60 deg F.
Specific gravities of various fuel oils:
No. 1 Oil: 0.82
No.2 Oil: 0.86
No. 4 Oil: 0.93
No. 5 Oil: 0.95
No. 6 Oil: 0.98
D. Heating Value
Heating value of a fuel is given in terms of BTUs per pound. This is the amount of heat generated when a pound of fuel oil is burned.
Heating values of various oils are as listed below:
No. 1 Oil: 137,000
No.2 Oil: 141,000
No. 4 Oil: 146,000
No. 5 Oil: 148,000
No. 6 Oil: 150,000
