The objective of the study is to find a relation for the predicting convective and evaporative heat transfer coefficient and distillate output for 200 mm and 160 mm water depth. In this present work an attempt is to be made to use inner glass cover temperature instead of outer glass temperature
as done by other researchers. The sides of the wall of the condensing cover are made up of FRP sheet to avoid heat losses from sides and to provide the desired inclination to the cover to the bath. It is exposed to room condition to increase the difference between water temperature and the condensing
cover temperature to increase the heat transfer rate and thus the condensate output.
