WebThermodynamics is the study of the relationship between heat (or energy) and work. Enthalpy is a central factor in thermodynamics. It is the heat content of a system. The heat that passes into or out of the system during a reaction is the enthalpy change. Whether the enthalpy of the system increases (i.e. when energy is added) or decreases ... WebExample 4: At WHP 4 bar g, well EX3 gives the following results when tested with a calorimeter (volumes are in liters, l ). The procedure to calculate the total mass flow rate and fluid enthalpy is: 1. For data in Run 1a: specific volume of water at 21°C, v1 is 1.0021 l /kg and at 53°C, v2 is 1.0135 l /kg. Using Eq. (8.8) the mass flow rate is.
