Experimental Study of the Effect of Reflection Mirrors Orientation on the Performance of Solar Still

الملخص

The present experimental work is a study of solar still with reflected mirrors. The solar radiation was calculated mathematically for angles ranging from 9^o to 30^o with 15^o increment for reflected mirrors and from 0-45^o with 5^o increment for glass cover. Experimental analysis showed that the best angle that intercept the maximum amount for solar radiation at the angle 85^o for reflected mirrors at the south-north orientation of solar still which indicates that as the slop of mirrors increase the average solar radiation decreases. Also the glass cover is inclined about 40^o. The study included the experimented test for the angle which may not permit the condensate to drip back into the basin. It was found to be 11^o.
