| dc.description.abstract | Solar energy is getting popular nowadays. Technologies have been developed which
made solar energy a cheaper and reliable source of energy. Due to pollution and other
factors, solar has become the most popular source of energy. Along with power
generation, now water heaters are also developed which are working on the solar
technology. It is a reliable method and can be used in areas which do not have access to
wood, coal and gas. This project is based on design and fabrication of solar water heater.
In this project, active water heaters are employed which way. Copper Pipe of both is
oval and rectangular used to compare the heat transfer. A motor will be suck water from
reserves tank to hot water tank and galvanized copper pipe will be heated from the sun
light. Between rectangular & oval pipe we found oval pipe heat transfer rate is more than
rectangular pipe. Local materials and manufacturing methods were used to fabricate the
solar water heater to limit the cost of project. At the end impact of the project was
discussed on social, economic and environmental grounds | en_US |
