Generally, manufacturers perform quenching of copper & its alloys pipes right after their extrusion from press. For better grains structure & efficient cooling of pipes, hot pipes are kept into water for a while. Cooling occurs due to heat exchange between quenching fluid & hot pipe by conduction and between hot water & surroundings by natural convection. Since the process of extrusion is continues, quenching of pipes must also be continues .However, conduction leads to rise in temperature of quenching fluid ,which in turn, adversely affects the continuity of the process. Also, rise in surrounding temperature affects worker's ability. To prevent these negative effects, we have to stop all processes until the temperature of hot water does not come into equilibrium to atmospheric temperature. Thus, low heat loss rate of quenching fluid poses problems during continues process. Therefore, Heat loss rate should be rapid & continues. To achieve this purpose, our objective is to design a cooling tower as per requirements, and measure its performance during process of heat exchange & quenching of pipes
