Pathak Assistant Professor Department of Mechanical Engineering Saraswati College Of Engineering And Technology, Rajpur, Kadi Abstract Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly.The process parameters such as inlet air rate, water flow rate and fills porosity have more influence on Thermal performance of cooling tower. The Temperature of outlet water is maintained nearest to inlet air wet bulb temperature to obtain the best Thermal Performance of cooling tower. So current work is to obtain and maintaining outlet water Temperature nearest to inlet air wet bulb temperature. The cooling tower fill is the most critical component in the operation of the cooling tower. The function of the tower fill is to provide a maximum contact surface between the water and the air to promote evaporation and heat transfer. Cooling tower fill accelerates the transfer of heat from circulating water by maximizing the contact area between water and air. So inlet water flow rate, inlet air rate and fill porosity are important factor to maintain the outlet temperature of water nearest to inlet air wet bulb temperature.

INTRODUCTION Blow Moulding Process Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison. The parison is a tube-like piece of plastic with a hole in one end in which compressed air can pass through. The parson is then clamped into a mold and air is pumped into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected. Fig. 1: Blow moulding machine
