EARTH SIZE MEASUREMENT IN SUMMER SOLSTICE USING “ÉRATOSTHÈNE” METHOD
The knowledge of solar deposit is very necessary in sizing and proper operation of any system powered by solar energy. Solar radiation data are used in the design development, construction, as well as in the solar energy systems performance evaluation, but also for the construction of buildings with a view to better thermal insulation adapted to the geographical location. According to the summer solstice 2022 occasion, in this work the measure of the earth radius is proposed using ’’Eratosthenes method’’. For this, three fundamental conditions have been taken for the correct application in our calculations. Which cities to choose? When to make the measurements? And what precautions to take? This document may be beneficial for students and the public
