Kuzmenko ozirno@ukr.net 1 NTUU “Kyiv polytechnic institute”, Kyiv, Ukraine Heat transfer coefficient for cooling tower is determined experimentally and theoretically, the latent heat and air flow heat to are calculated. Thickness of heat layer is calculated and is then compared to theoretically calculated the displacement layer. The heat transfer coefficient is calculated based on the values of displacement layer and its deviation from theoretically calculated one is up to 3 times in the range of air velocity of 1.3-3.0 m/s. The difference in temperature of the air and water film is calculated. http://pubs.sciepub.com/ajer/2/3/1/ajer-2-3-1.pdf cooling tower heat transfer displacement layer Merkel equation
