The Canvas were tested with water, and the results obtained were as shown below:
Day 01:
Room temperature - 29ºc
Initial water temperature - 23ºc
10.30 am - 23ºc
11.00 am - 21ºc
11.45 am - 20ºc
12.45 pm - 19ºc
01.45 pm - 19ºc
02.45 pm - 19ºc
Temperature difference of 4ºc in 2 hours and 15 minutes.
Day 02:
Water taken in this day was hot water.
Room temperature - 26ºc
Initial water temperature - 37ºc
09.45 am - 37ºc
09.55 am - 35ºc
10.25 am - 30ºc
10.55 am - 28ºc
11.25 am - 25ºc
12.00 noon - 24ºc
12.30 pm - 23ºc
01.15 pm - 23ºc
01.45 pm - 23ºc
02.45 pm - 22ºc
Temperature differences initially were high and later it slows down.
The experiment was conducted in the night time.
Room temperature - 23ºc
Initial water temperature - 23ºc
06.15 pm - 23ºc
07.15 pm - 23ºc
09.45 pm - 22ºc
11.00 pm - 22ºc
12.15 am - 22ºc
09.00 am - 21ºc
10.00 pm - 21ºc
Result:
In the night the outside temperature is low, so the water cooling happens very slowly. The water cooling will happen faster only when the outside temperature is high.
