Saturated Steam - Properties for Pressure in Bar

Enthalpy /ˈɛnθəlpi/ (listen), a property of a thermodynamic system, is the sum of the system's internal energy and the product of its pressure and volume. It is a state function used in many measurements in chemical, biological, and physical systems at a constant pressure, which is conveniently provided by the large ambient atmosphere. The pressure–volume term expresses the work required t… Webenthalpy of the evaporated water in the air - the latent heat; The total enthalpy - sensible and latent - is used when calculating cooling and heating processes. Specific enthalpy - h - (J/kg, Btu/lb) of moist air is defined as the total enthalpy (J, Btu) of the dry air and the water vapor mixture - per unit mass (kg, lb) of dry air. burnley west brom stream
