Performance Evaluation Of A Solar Still

ABSTRACT There is an urgent need for clean potable water in many countries of the world including Nigeria. While most urban populations have access to clean potable water many people in rural areas do not. There are many ways that can be used to improve the quality of water and one way is through distillation. This work aimed at producing potable water from brackish water for both rural and urban dwellers. The solar distillation plant used in this experiment has collecting area of 0.68 m2 . The emissivity of glass cover and absorbtivity of the absorber plate are 0.85 and 0.93 respectively. The experiment performed gave maximum distillate of 2.3 litres on day 5 and maximum temperature of 54C on day 5. From fig 2-6 it was observed that as solar intensity increases the higher the production of distillate
