Abstract: | This paper presents the results of investigations carried out over a solar still coupled with an inexpensive solar ground water heater. The explicit expressions for water temperature at the outlet of water heater, glass and water temperatures in the case of a solar still in which the hot water is flowing at a constant rate, have been derived. To appreciate the enhancement in the still productivity, numerical calculations have also been carried out for two typical days at Delhi, India. |
