Popsicle Question!!!!

Im going to make juice popsicles but I dont have tooth picsWhat else can I use? Thank You!! :-] Bye.

Answer:

You are making a heat exchangerOne way to do this is to run water through a very large radiator like a Semi truck radiator and air through the other way using fans and pumps but chilling the water is the problemOne way to remove the water from the air is a squirrel cage separator like in aircraftThe air is forced through a funnel to compress it then a tube then through an expander, like a funnel backward through a turbine into a fiberglass bagThe bag is on a wire frame which is spinningWith the air going through the pressure drop area the moisture condenses on the bag and gets slung off to the walls of the tube it is inside ofThe water runs down the walls to a drainThe dried air passes out the other end through a tube into the roomFiberglass is used in the bag because it doesn't soak up water and doesn't rustYou will need pumps and blowers and a chiller unless you use cold tap water.
My uncle used this system to cool his house for yearsHe hada flowing well and passed it through a truck radiatorAll the condensation takes place in the fins of the radiator so you just have to provide a drain for thisthe costs for such a system are very low and you don't end up with high humidity air.
YesThat is the way air conditioners work, although they use something other than waterYou will need a method of replacing or cooling the warmed water.
It can workBut the air temp will be limited to the water temp, unlike a system that works off of compression/expansion or evaproation, where the cooled medium can go below the environmental temperatureAnd as the rate of heat exchange is proportional to the temperature differential bewtween the air and water, the exiting air will likely be a few degrees warmer than the waterThis may or may not be acceptable for a given applicationYou would also have to see how much air would need to be chilled in this manner to cool whatever it is you want to cool, to determine if this method would be practicalLook up the specific heat content of air and compare it to how many watts or BTU's have to be removedThe wider the tube and the faster the air moves in the tube, the longer the tube has to be in order to get an acceptable amount of cooling.
bbq skewers or roll up some aluminum foil into popsicle stick shapes and use them.
