What water temperature to use for sizing a cooling tower (part 1)

An industrial water cooling tower uses air from the environment as a cooling element. Until some time ago it was very difficult to find data values for temperature and humidity, simultaneously, needed to calculate the air enthalpy and to obtain significant design data in order to size the cooling tower in an economic way.

My first job was to create diagrams from wet-bulb data tables received from meteorological observatories, airports and other areas where it was possible to find data tables, moreover, still fragmented. This was the only detected simultaneous data available and, hence, used for air enthalpy statistics.”
