    Programs Thinking on getting my a PhD in physics.

    Absolutely nothing to do with this threads subject, but I laughed from one of the comments and I can't hold myself from mentioning that I know a guy who is actually a Doctor-Ninja-Lawyer (not a firefighter though...). He deals with medical negligence lawsuits and practised Ninjutsu for many...

    Why Does Misting Fan Cool Air?

    Thank you for the succint answer. That raises another question then... So, youre saying that water vapor is cooler than the water it escapes from? But when water evaporates, doen't it increase its particle speed?

    Why Does Misting Fan Cool Air?

    So, as far as I know evaporative cooling is when the top layer of a material (lets say water) evaporates- taking energy with it leaving the rest of the material cooler. Also leaving the air, which transported some heat to it, cooler. But in a misting fan, the mist evaporates, takes energy...

    Suppose i have a bucket full of water in a closed room,the water is

    Not exactly what I asked but it helped me to figure out, :P Another quick question- When gaseous particles move due to their heat/energy, their motion would be endless if they wouldn't collide with anything? If so, then wouldn't that mean that potential energy turned into work, meaning no...

    Suppose i have a bucket full of water in a closed room,the water is

    Umm...ok I understand what you are saying... But how does this coincide with: "Entropy is a thermodynamic property that can be used to determine the energy available for useful work in a thermodynamic process..." (Wiki)? Thanks.

    Suppose i have a bucket full of water in a closed room,the water is

    Hi, A quick question from someone who don't know how entropy works- Why do molecules in the air have more enthropy than those in the water? I thought that "entropy" is the amount of energy that can do useful work. Aren't the evaporated molecules in the second stage after doing their work...

    Evaporarive cooling. How to calculate the cooling of the air?

    Hey, So I'm trying to figure out how effective evaporative coolers are... Lets say, I have a box with 3 cubic meters of air with a humidity of a 10%. I blow it out with a fan and spary with water as it leaves the fan. The water is room temp (which is let's say 27 C). What temperature...
