EXPERIMENTAL HEAT TRANSFER RATE ON VERTICAL PIPES OF A SIMPLE WATER HARVESTER
One of the tools that can be used to produce clean water is a water harvester. However, this tool is still very low in water production, so it needs to be investigated to increase its water production. This study examines the heat transfer rate from the air to the outer walls of pipes of an evaporator used in the simple air-water harvester. The pipe lengths that varied were 20cm, 40cm and 60cm which were arranged vertically with 138 pipes. The corresponding heat transfer areas were 0.2008m2, 0.3534m2 and 0.5039m2. The results showed that the highest freshwater mass was 308g/7 hours found at the heat transfer area of 0.3534m2, while the highest total heat transfer rate obtained was 59.6W. This study could be used as a reference to design an evaporator of a simple air-water harvester.
