  • @Purifiedinfire Dear crony, Thanks for your reply. Well just wondering if the idea is to evaporate only through the string then why we did not provide a single narrow path for evaporation? In my viewpoint, there should not be much effect by the length of string as the wet bulb temperature is supposed to be measured uniformly that's why we keep the whole bulb covered with the string, once the string gets wet, the wet bulb temperature is not going to change. Any suggestions on it plz?

  • @zaman866 I believe you want to keep it short, the whole idea is that the water needs to evaporate and make it's way through the string. The evaporated water vapor may not be able to make it up a long piece of shoe string.

  • Thanks for the video...This is awesom...Just want to ask what if I choose a LONG shoe laccee..that is putting the thermameter for wetbulb near the top cap of the bottle and dip a long laccee near its bottom....WILL IT MAKE ANY DIFFERENEC?????? EXPLAIN LOGICALLY PLZZZZZ

    Plz reply via this message...Thanks!
