Abstract
This paper presents the results of the experimental investigation on a solar flat plate collector carried out at Coimbatore, India (11°N Latitude and 74°E Longitude). The collector tubes allowed the water to flow twice across the flat plate collector using a circulating pump during which the water gets heated by the solar radiation received by the absorber. The maximum temperature of water obtained on a typical day in the month of April was 64°C with a solar radiation of 932.2651 W/m2. The available solar radiation strongly influences the temperature gain of the system while the wind velocity plays a considerable role in influencing the heat lost by the system. It is observed that the two-pass flow of water across the absorber plate results in a maximum temperature gain with an overall collector efficiency of 43.7 %. This solar water heating system using flat plate collector can be used for small-scale desalination applications.
