This paper presents an experimental work, which studies the performance of a counter-flow type cooling tower. The experimental trials have been carried out in a counter-flow type cooling tower test rig with mechanical draft. Expanded Wire Mesh type of film packing has been used for experimentation. The packing is made of mild steel with height ranging from 800 to 1255 mm. This study investigates the effect of the air and water flow on the cooling tower range, as well as the tower characteristics for different air flow and water flow quantities. The variation of temperature along the height of pack is measured by means of suitable thermocouples at five different places. The results show that the mass flow rate has adverse effect on the number of transfer unit. Also tower range would be increased by decreasing the inlet wet bulb air temperature.
