Thermodynamics

enthalpy of formation

Physics; Thermodynamics

The enthalpy of a substance at a specified state due to its chemical composition. The enthalpy of formation of all stable elements (such as O2, N2, H2, and C) has a value of zero at the standard ...

enthalpy of reaction

Physics; Thermodynamics

The difference between the enthalpy of a product at a specified state and the enthalpy of the reactants at the same state for a complete reaction.

sling psychrometer

Physics; Thermodynamics

A device with both a dry-bulb thermometer and a wet-bulb temperature mounted on its frame so that when it is swung through the air both the wet- and dry-bulb temperatures can be read together.

chemically correct amount of air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

theoretical amount of air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

stoichiometric air

Physics; Thermodynamics

The minimum amount of air that supplies just sufficient oxygen for the complete combustion of all the carbon, hydrogen and sulphur present in the fuel.

air-fuel (AF) ratio

Physics; Thermodynamics

A variable used in the analysis of combustion processes to quantify the amounts of fuel and air for optimal performance. It is usually expressed on a mass basis and is defined as the ratio of the ...
