How to Calculate the Change of Enthalpy
Enthalpy, h, is a thermodynamic property of fluids used extensively when analyzing flow problems in fields such as fluid dynamics or aerodynamics. It is defined as u' + p/(rho), where u' is specific internal energy. Enthalpy is used to defi... Read More »

How to Calculate Enthalpies
Typically, enthalpies of reactions need to be calculated. Enthalpy (abbreviated as "dH") is the amount of heat absorbed (dH >0) or released (dH<0) in a chemical reaction. Enthalpies are usually computed at standard conditions (the pressure ... Read More »
