Cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. This paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. The tower is filled with ۶ type packing. In this study temperature and pressure drop and tower characteristics was used in determining experimentally the thermal performance of the cooling tower. Temperature drop decreases as water mass flow rate increases, pressure drop increases as mass flow rate ratios increases and tower characteristics increases as water mass flow rate increases. The data registered in the experimental set up were employed to obtain correlation of the tower characteristics.
