An Experimental and Statistical Analysis of Double Slope Single Basin Solar Still in Active and Passive Mode with Different Water Depth.

Abstract

In the present work, experimental work on double slope single-basin still is investigated. The statistical analysis shows the effect of various factors related to the efficiency of still. The water level in the basin investigated at 10 cm, 6 cm and 2 cm depth. The process temperature TW, TG and TB were recorded one each day. The still is used in the Agra city climate. The mode of operation affects its water yield as an active mode of operation produces more water yield than a passive mode of operation. In the statistical analysis R2=99.29 (passive mode) and R2=99.11 (active mode) recommend the satisfactory agreement of the factorial design regression model.
