| Summary: | Water mist heads are used in close areas to provide direct and constant mists of water for rapid cooling, watering plant, and fire extinguisher. Majority of the water mist’s types in the market has certain problem such as need high pressure and high water volume. Thus, the main aim of this study is to determine the best design of the water mist head. From literature review, the author identifies two parameters as a major concerned, i.e. pressure and flow rate. Three water mist’s head prototypes have been produced using RP machine. Then, the experimental works have been conducted with six test configurations, combination of three pressures and three diameters, to determine the mist patterns. For water pressure, the analysis is on 1.4, 1.8 and 2.2 kgforce and for diameter used in range 0.5, 1.0 and 1.5mm. The measured variables are the length of mist spread out from the nozzle. The result show that the optimum design is for the case 7.5mm at pressure 1.8bar and diameter 1.5mm for nozzle with designed internal flow and 20mm at pressure 2.2bar and diameter 1.0mm for nozzle with normal internal flow. |
