-
Horsepower hour is based on mechanical horsepower which can differ regionally
-
Conversion does not include efficiency losses in engines or equipment
Frequently Asked Questions
-
What does fuel oil equivalent @barrel (US) represent?
-
It represents the energy contained in one U.S. barrel of fuel oil, used to express petroleum volumes on an energy basis rather than volume.
-
Why convert fuel oil equivalent to horsepower hour?
-
To translate fuel oil energy volume into mechanical energy terms useful for comparing engine output or conducting energy accounting.
-
Does the conversion account for energy losses in engines?
-
No, the conversion reflects theoretical energy content and does not include efficiency or other losses in machinery.
Key Terminology
-
Fuel oil equivalent @barrel (US)
-
The energy content contained in one U.S. barrel of fuel oil, used to express petroleum volumes on an energy basis rather than a volumetric basis.
-
Horsepower hour [hp*h]
-
A unit of energy equal to one mechanical horsepower produced continuously for one hour, representing mechanical work output.
