This project determined the process of cooling of cooling tower with force draft type, splash plastic packing and created the model of cooling of cooling with splash plastic packing.To design the tower with area is 7x7 inches high 14.7 inches and test with the condition is constant of the volume flow rate and inlet temperature.in experiment used the value of volume flow rate is 130 ml/min,140 ml/min,150 ml/min and in let temperature is 50 ,60 ,70 ,80 operate at every flow rate
