Also,  most engineers (if not all) would not use the term "Combustion enthapies". They would use either "Heating value"  or "Calorific value" and they would make sure to state whether the values are "gross or net" ... (or "higher" or "lower"). The "gross" ("higher") value is when the water in the combustion product gases is in the liquid state and the "net" ("lower") value is when the water in the combustion product gases is in the vapor state. Thus, Net (Lower) value = Gross (Higher) value - heat of condensation of water. Personally, I prefer the terminology "Higher heating value" and "Lower heating value" ... or "Higher caloric value" and "Lower caloric value".

Paul, this is a comparison of your HTML table with a Wiki table. Some editors may prefer the Wiki table. The Wiki markup coding for the Wiki table can be seen on the Edit page of this sandbox.

Also, most engineers (if not all) would not use the term "Combustion enthapies". They would use either "Heating value" or "Calorific value" and they would make sure to state whether the values are "gross" or "net" ... (or "higher" or "lower"). The "gross" ("higher") value is when the water in the combustion product gases is in the liquid state and the "net" ("lower") value is when the water in the combustion product gases is in the vapor state. Thus, Net (Lower) value = Gross (Higher) value - heat of condensation of water. Personally, I prefer the terminology "Higher heating value" and "Lower heating value" ... or "Higher caloric value" and "Lower caloric value". Whether you use "heating value" or "caloric value", the values should be stated as either "gross" ("higher") or "net" ("lower").
