Periodic theory of solar still

Abstract

This paper presents a periodic analysis for estimating the distillate output of a single-basin-type still with large water depth, when the still (i) rests on the ground and (ii) is mounted on a stand. Our observations on the mounted still are in good agreement with the theory. the theory also provides theoretical basis for two well-known experimental results, viz., (i) The daily yield of the distillate is independent of the insulation in a ground still (Bloemer et al.1), (ii) The daily yield of distillate for a large mass in the water basin in independent of the water mass.
