25+ Heating Value Of Natural Gas Btu/Lb US. 1 btu/lb = 2,326.1 j/kg = 0.55556 kcal/kg. Volumetric heating values are based on standard temperatures and pressure of dry gas.
A btu measures the heat value of natural gas. The heating value or calorific value of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. Heating value is a quantitative measure of heat content of a natural gas.
Use btu/ft 3 and btu/lb instead of kj/m 3 and kj/kg.
This video provides a guideline on how to calculate heating value of natural gas with some. Btu = british thermal units; The percent efficiency is dependent on the heating value of fuel oil (measured in btu) and shows a strong positive correlation. The british thermal unit (btu or btu) is a traditional unit of energy equal to about 1055 joules.
