popco - in addition to what hacksaw said, you need to sheath your thermocouple - or use a non-contact temperature measurement.
The reason for the loss of stability in readings is the electrochemical processes occurring in the nitric acid around the thermocouple: on one hand, you are trying to...
John, I think it (at least one of). Probably because on most other threads, a person would receive a satisfactory response and go on back to work. Here it is just a way to talk about serious issues with a smile.
Hey Tom,
Actually this has been bothering me ever since, but I decided never to proceed with experimentations in that direction anymore: what happens to the hot milk and vodka in an acidic environment at 37 degrees C? What exactly was it that decided to shoot up? ;)
LOL, Tom! I wouldn't even think about it (milk + root beer). I once mixed hot milk and vodka (I was then a young and stupid ChemE student, and it was on a dare) inside of me. Yuck!
Seriously, I think milk and root beer would cause a different kind of foam: extremely dense, with very low...
Tom, WoW! That was a cool dissertation there. Your spelling of "SUPERSATURATION" and "NUCLEATION SITES" was immaculate :) Would you mind addressing the issue of pouring cola onto ice cubes (variation of amount of fizz with the size / shape of ice and other materials) and...
That's a good point! Also, ice melts into the cola, which complicates the big picture, as it may alter the solubility product for CO2 in the mix.
BTW, here's another question: which way will ice alter the "fizz" compared to plastic or glass? I wouldn't bet my paycheck on it, but I...
Railbaron, that's a good one! I think it does so because the ice cubes work as packing in a stripping column: they develop the phase contact area, thus increasing the efficiency of this desorber. Try doing it with different ice pieces in shape, size, and order (vs. random) and see how it comes...
Steve, be careful about sucking out the CO2 from carbonated drinks: once you apply vacuum to the Coke bottle, you will lose your CO2: the partial pressure of dissolved CO2 in the Coke bottle will become higher than the partial pressure of CO2 in the space above the Coke, and it will want to...
Steve,
I applaud your scientific curiosity. While I agree that the tongue of a Coke afficionado is a very sensitive tool, [thumbsup]the first thing to do when doing any research is to make sure your gauges are OK. You need to perform gauge R&R first, in other words get a consilium of 3-5 Coke...
I completely forgot how to evaluate scrubber capacity. If I need to remove 98% of the contaminant in the gas, then how do I go about calculating whether or not this scrubber is up to the task? I have all the data, short of packing
