ABSTRACT

Energy is essential for living and vital for development of all. The global economy thrives on energy. Affordable energy directly contributes to increase productivity, reducing poverty and improving betterment of life. Global population is increasing day by day, which, in a way is leading to the utilization of natural resources and fossil fuels. The solar energy, wind energy and bio mass are three major sources and out of these three energy sources solar energy is the easiest source to extract useful energy because the wind energy can be useful particularly in coastal area where there is high wind velocity and energy extraction bio mass needs either chemical conversion or thermo chemical conversion process. The objective of present work is to carry out comparative study for thermal performance of the helical solar heater of various coil pitch by using Digital Thermometer at appropriate location of both experimental set up; using thermocouple the change in water temperature for 20 litre water will be carried out simultaneously in case of two set up will be fabricated
