©2018 ACCENTS 1.IntroductionNature's gift i.e. water plays an important role in developing and under developing countries. Major problems now a day facing whole world is availability of fresh water for drinking [1]. In the polar region 2% of water is available in fresh form and 1% is being used by humans, plants and animals in their daily life and remaining is in the form of salt water (i.e. Ocean water) [2]. Major health issues are caused due to water contamination. Due to insufficient rain fall salinity water increased rapidly in major parts of the world. The possession of polluting water increases drastically due to increase in population and increase in industrialization, which results affecting the agriculture in rural areas and availability of unreliable fresh water in urban areas. Increase in desertification and drought in worldwide results in shortage of fresh drinking water which is now a biggest problem in the world [3].Current growth in increase in population which may reach up to 800 crores by 2025 (Prediction), reduces water per capita. Two third of population may receive contaminant water due to pollution and exhaustion of water supply by the end of 2025 [4]. Most of the females spend their time in collection of water. *Author for correspondenceDue to untreated water around 3.575 millions of people die in the world due to contamination of water which causes major health issues in rural areas [5].The best solution to overcome the health issue in rural is water purification using desalination. Solar distillation is one of the best method in rural areas, as solar energy is abundantly available in rural areas [6]. Hydrological cycle i.e. evaporation and condensation process is one of the economical technology which can be used both in rural areas and urban areas all over the world for purification water using solar distillation unit (SDU) [7,8].Basic principle involved in SDU / still is evaporation and condensation. The polluted water in the SDU is first heated by solar radiation which passes through the top cover and causes evaporation. Difference between the glass cover and water leads to condense water leaving contamination in still. 2.Solar distillationEarth surface is covers about 77% of water, most of them are either in ice bergs or sea water located at Polar Regions. Water available in form of salty water, and less quantity of fresh form of water which is >1% what is being used by living beings now a days. The problem of purification of water can be solved by using hydrological cycle. Distillation of

Karakteristik Termal Kolektor Pelat Datar Model Serpentine Pada Pemanas Air Tenaga Surya

“…Konfigurasi model pipa serpentine-paralel dan model paralel-serpentine pada pipa fluida pemanas air tenaga surya sistem thermosiphon, hasil yang diperoleh efisiensi panel kolektor dengan konfigurasi paralel-serpentine lebih besar dibandingkan konfigurasi serpentine-paralel. [10] Pada pemanas air tenaga surya dengan konfigurasi pipa model serpentine memiliki konstruksi yang lebih mudah dibandingkan konfigurasi pipa model paralel yang memiliki banyak sambungan pengelasan pada pipa [11].…”
