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 ...
