Present situation Future work Some insights Inference Our Quaries Tilt angle Tilt angle The loss in the amount of collected energy is less than 1% (0.97) if the angle of tilt is adjusted seasonally instead of using opt for each month of the year. The loss of energy when using the yearly average

Present situation Future work Some insights Inference Our Quaries Inference Inference We require an air ow rate of 1.778x103 m3=s (1.77 l/s) to aquare 10 l of water in a day. Currently we have only .0119 l/s of air through tube. Which means we want to rise the air ow rate 148 times. If tubes are limited to 10 No's then ow rate should be 0.177 c/s. Then the time for collecting 0.4 lof air would be 2.249 sec only. Aim The ow rate should be increased Temperature of Inlet air should be increased 16 / 18
