STUDIES ON FINNED BASIN SOLAR STILL

In the present work an attempt has been made to improve the heat transfer rate from basin liner to the water. Fins are used in the basin of the still to increase the heat transfer rate. Performance of a finned basin still is compared with that of a conventional still. It is observed that the productivity of the still increases with increasing the numbers of fins. When number of fins increase thrice, productivity increases by 25% as compared with the conventional still. Daily productivity increases with increasing number of fins in the basin.
