A STUDY OF THE EFFICIENCY OF VARIOUS DESIGNS OF SOLAR STILLS FOR PRODUCING POTABLE WATER
MAUNG NAY HTUN and M.P. AFTABSummary: The design, construction and operation of six different types of solar stills is described. The average production rate of a conventional solar still is found to be 2.50 l.m-2day-1 with an overall efficiency of 28.45 percent. Internal and external mirrors attachments to the still will give 20.32 and 58.20 percent higher production rates respectively. However, decreasing the depth/width ratio of the still from 1:9 to 1:3 will decrease the production rate by 44.22 percent. Environmental Engineering. Division, Asian Institute of Technology, P.O.
