Comparative Performance evaluation of an active/passive solar Distillation system

Abstract

No water, No life, No blue, No green. It is key for people prosperity. Human body uses water for all biological processes like digestion circulation transporting nutrients etc. The average consumption of water by human is 2.5 to 3.5 liter per day. In this methodology attempts has made to find out the effect of water depth on evaporative mass transfer coefficient of a passive single slope distillation system summers. The experiments has been conducted on south facing, single slope, solar still of 30° inclination of condensing cover, in summer climate for 24 hrs. on different five days for different five water depth from 0.04 to 0.18m.Objective is to study the variation in internal heat transfer coefficients depend to water depth in the still. © 2017 Elsevier Ltd.
