Experimental investigations to reduce unwanted evaporative losses of drinking water from a clay pot

Clay pots are being widely used in hot-arid/tropical regions for reducing the temperature of the drinking water and this is due to the evaporative heat losses from the clay pot surface. However, excessive water loss from the surface is inevitable as the clay pot is porous. In this paper, strategy to reduce such unwanted water loss has been presented. It has been observed that more than 50% of water loss can be reduced without compromising the cooling effect.
