even if the tygon does not take any affection from the alcohol, how bout the rubbers in the pump? Mr. Sniper, pls keep updating us with your observation.

haha... if add in a ratio 1:10 hmmm lets see...
assume the whole loop take up 1lit++ of water.
100ml of vodca shall be added.
1lit of vodca = RM75
100ml = Rm7.5

not so exp also ... how if i wan the liquid to be blue color? does adding golden bleu giving same effect as vodca?

u try lor... update us the outcomes

i think tygon would survive from the alcohol since most of the laboratories use them because of their chemical resistive (not all unfortunately). yea, dump in some plastic or rubber made stuff, such as o ring would be good for experimenting.

Edit : Oh crap, guys, there is no point for us to continue this test anymore. the ingredients for vodka consists of various types of flavorings, water and alcohol. and i just found out that the alcohol used by vodka is ethanol based. ethanol has a viscosity of 10.7 × 10-4 while water has got a viscosity of 8.90 × 10-4 (both in the unit of Pascal second and both in the temp of 25 degree celcius). so there is no way for vodka's viscosity to be lower then water somemore there are so many types of flavoring added to the vodka wic would greatly decrease the viscosity of it. and also the evaporates theory doesn't make any sense in this case because its in a closed loop, and liquid shall not be able to evaporate. maybe i'm wrong, so do correct me.

note : the smaller viscosity it has, the faster the liquid flow.

with these, i raised a few question,
1 - Ethanol greater than 50% is easily flameable. This property is where plastics/rubber are prone to disolve. With this, does it ever means that 25% of alcohol will do any harm to the plastic or rubber?

2 - Absolute ethanol boiling point is 78.4 °C. Ethanol has a heat capacity of 2.4 J/g K, while water has a capacity of 4.2 J/g K. Therefore water has a higher capacity to store heat energy, while alcohol has a higer ability to disipate heat.
The heat capacity and boiling point does not simply determine the heat transfer capability of a liquid does it?

3 - just to confirm, alcohol does not corrode copper and brass does it?

erm... ok, like this, wat happen to water at its boiling point? CPU reaches 70C does not mean tat the liquid in it would also be heated up to tat temp. there would always been heat losses during the heat transfer. copper does not fully transfer the heat generates by the CPU. aiks... i make this so complicated. not good in explaining. (so just for u to understand, CPU temp is always 8~20 degree higher than liquid used to cool it.)

yupe, it indeed depends on the liquid used. however, liquid used in our daily WCS is quite limited. does not really agree upon the bold part above. tat condition does not apply for life water.

who knows. but i really really think that the best improvement (if got) would not be more than 2degree C.

so drank the vodka?
