Humidification is a core factor in air conditioning, agriculture, industry, and health applications. Many humidification techniques were used in the literature, and the humidification and evaporative cooling from multi-wet cylinders were investigated in this study. An experimental test rig was constructed to perform tests. The air temperature and the number of wet cylinders were varied and tested, experimental results were recorded and validated with theory, and the maximum error was recorded to be 3.3%. It has been noted that the relative humidity drops by increasing air temperature as expected from the literature. The use of multiple cylinders has the effect of humidification and evaporative cooling. The more the number of wet cylinders the more the evaporation rate. As mα = 0.0975 kg/s with an almost constant wet bulb temperature of 9 C, the amount of water evaporated was calculated as 73.7, 130, and 263 g/h for single, double, and triple wet cylinders respectively.
