The study of air velocity inside the cooling tower gives an overview of the process of heat or mass transfer. This study developed mathematical modelling based on the principle of continuity and statistical thermodynamics to track changes in radius, velocity, density, and temperature of droplets and air along with the droplet trajectory or tower height. Before that, the droplet radius range is predicted in advance to get the accuracy of the calculation. Also, water capacity and fan rotation are varied to determine their effect on cooling tower performance. The calculation results showed that 18 Lpm capacity gives efficiencies above 50%, while for 0.5 Lpm capacity, it produces efficiencies in between 25% to 40%. The highest efficiency indicates that the evaporation process occurs most efficiently. Mathematical modelling in calculations can also describe the increase in air temperature, which usually uses numerical simulations.
