Fuel oil in a day tank for use in an industrial boiler is tested with a hydrometer. The hydrometer reading indicates a specific gravity of 0.838 when the temperature of the fuel in the tank is 38.8 degrees Celsius. Calculate the higher heating value of the fuel in BTU per pound using the ASME formula for petroleum products.

The higher heating value represents the maximum amount of heat released during the complete combustion of the fuel. the value is 1478.75 BTU per pound.

The higher heating value of the fuel oil in BTU per pound, we can use the ASME formula for petroleum products. The ASME formula is:

[tex]HHV (BTU/lb) = 1478.3 - (1.125 × SG) + (0.0116 × T)[/tex]

Where:
- HHV is the higher heating value
- SG is the specific gravity
- T is the temperature in degrees Celsius

In this case, the specific gravity (SG) of the fuel oil is 0.838 and the temperature (T) is 38.8 degrees Celsius. Let's plug these values into the formula:

[tex]HHV = 1478.3 - (1.125 × 0.838) + (0.0116 × 38.8)HHV = 1478.3 - 0.94125 + 0.44928HHV = 1478.74803[/tex]

The higher heating value of the fuel oil is approximately 1478.75 BTU per pound.

This value is useful for determining the energy content of the fuel and its efficiency in heating applications.
