Dual pumps in a bong?

[Monaco]

Seems simple enough. I have a low power pump, 70GPH at 1 foot. I'm thinking about using it just to pump water UP, through an atomizer nozzle, from the bong's base. It'll just shoot mist straight up the tube, I'll use another, better pump in the base to actually move water thru the system.

I thinks misting it like this will increase surface area and thus, cooling I hope.

Does anybody have any comments on this? Do you see any flaws?

hmm, the only thing I can think of is if the pump doesn't spread the water out, if it shoots it in a fine stream. If it does that, I don't think that it would work very well. Although if you have the pumps already, it definitely wouldn't hurt to experiment with it.

the only pump I have to play with right now is the 70GPH.

I'm hoping a spray nozzle would spread out the water in an umbrella-shaped mist. Hoping!!

The water coming out of the waterblock is warmest. You might want to separate it to another reservoir with that tiny pump to let the pump do its trick first instead of mixing directly with the main reservoir and having it warm up the cool water. The thing here is that most ppl spray the hot water directly after coming out from the waterblock so when it mixes with the reservoir water after being cooled while falling as droplets, it has already lost the waste heat. Anymay misting is bad in the sense that it'll be easily blown away by strong fans and you'll lose more water than you should.

Is the coolant loss such a big problem? Are there some things that can be done without reducing the effectiveness? I justt would like to know :)

ctjune I don't think I quite understand what you mean. My plan is: the small pump is constantly spraying water up the bong, thus cooling it. The system pump will draw in water cooled by the small pump and then move it thru the waterblock. It will then go back to the res to be cooled again by the 70GPH sprayer pump.

I'm not worried about coolant loss: I live in Denver, it is dry as hell here, my room could use the moisture.

Idea: I'll connect the input of the sprayer pump to the output of the waterblock, so the sprayer pump only "sees" heated water.
I think I'm gonna draw a picture to explain.

Monster, the warmed water going into the reservoir will mix the the cool water. Your 70gph pump will then pick up the mix and mist it. The problem is that your won't be cooling the wamed water first like most bongs do as it first comes out from the shower head, drips, evaporates, cools, and then finally hits the rest of the water in the reservoir. Your setup cools lukewarm water and will most likely will supply lukewarm water to your 'block!

I never thought about that, cjtune. Damn. Well, I'm gonna experiment some and if it ends up being any good I will post again. Maybe a dedicated cooling pump will overcome the lukewarm problem you describe. :(

if you really want to use 2 pumps you could try linking 2 bongs together. I havent seen any results tor that yet. but if you usea lower rated pump to supply the water for the bgger pump the bigger pump will suck its self dry and visaeversa. that is the problem i see with using 2 different sized pumps.

Wow, I just wish I had room for two cooling towers. Although I doubt it would be worth it, unless you had some peltier action going on.

I AM doing a little testing with another idea, the 1 pump per waterblock system. Little pump on GPU, big pump on CPU, shared reservoir. No benefit so far, but it needs tweaking.
