ABSTRACT This experiment was conducted to perform energy and mass balance on the cooling tower system and to observe the effects of one of the process variables on the exit temperature of water. For water cooling tower experiment, there are several parameters that can be adjusted to observe its effects on the evaporation of water. The parameters are temperature and flow rate of water, relative humidity and flow rate of air and cooling load. In this experiment, we choose the cooling load as variable while water flow rate and flow rate as constant parameters. The steady flow equations which is energy and mass balances were employed in order to provide an insight on the amount of energy transferred between phases under different conditions. The energy transfer calculated from the experiment for cooling load of 0.5 kJ/s , 1.0 kJ/s and 1.5 kJ/s.
