I like the simultaneous posting of nearly identical replies in different words. I'll call it the dueling banjos.
I have 10+ 120BBL(bbl =31 gal) fermentation tanks pumping out massive ammounts of co2 through blowoff tubes that are leading down to floor level (where we work) Those blowoff tubes for 3700galons of beer are put into a 5 gallon bucket filled half way with water. The bubbles the first two days of fermentation are so vigorous that water has to be replaced in the buckets numerous times a day. The co2 from 37,000 gallons of freshly fermenting beer spilling onto the workfloor with doors closed (winter time) has not killed a single person yet in more than a decade. I highly doubt the handful of small (literally bedroom sized) ceiling fans that dot the ceiling (on low speed if at all on) four stories above move enough air.

Carbon dioxide is formed during the alcoholic fermentation of the grapes. Because it is 1.5 times heavier than air it sinks to floor level - the bottom of wine vats or in wine cellars. The gas is odourless and colourless, meaning that ventilation and carbon dioxide testing during the wine-making process can become life-saving. A concentration of just eight per cent is enough to kill a human being.

That article is wrong....but wait, that cannot be, It's on the internet.......it must be true....
Believe what you wish...it is pointless to argue about it.
But if co2 actually sank, no one would ever be able to sleep on the floor.
That is pretty much self explanatory.....

c02 its self is heavier then oxygen BUT it mixes with oxygen then diffuses quickly... so it doesn't sink because it mixes with other gases.

co2 is always present, but in a place like a box, or a wine cellar specially with fermenting wine or in the box mycelium that produces co2, the levels are higher.. thats it
RR's qoute on we all be dead is false, air is moving due to the temperature changes google how wind is present.
co2 in less ventilated places collects up at the floor level. end of story, do your homework, and give proper advise to this poor guy trying to make the monotub..
if RR was right, no one would die of suffocation if co2 present in a room, which can occur quiet often in less ventilated rooms..

Extra extra read all about it
Erbudy dying at wineries these days. While no one is dying at breweries? Either way CO2 can buildup in things like mine shafts or valleys that are volcanid but not in your fruiting chamber. Mushrooms don't make that much co2

u didnt get it did u.
the levels were so high that it filled up the whole place, like pouring water into a glass the water level rises..the co2 level in the air was that high..

In the case of the wineries it's not sinking co2 either it's replacing the air with co2. You're purging air with a co2 firehose from fermenting wine. It's making so much for such a small space that you're diluting the concentration of other components of air just piling underneath them.

Yes, but it does not sink.....it is just at a higher concentration mixed in with the air.....none of this proves that it sinks......

just read that answers everything..... same discussion were having.
Quote:
But the petrol fumes would not stay for very long at ground level. Convection current carry them upwards, and gaseous diffusion would cause mixing with air even without convection. That's because gas molecules are in a state of constant motion, colliding with other molecules, millions of times a second, causing them gradually to diffuse ("spread") in all directions. The fumes gradually spread into all the space available - which could be a jar, a garage, a hangar, the entire atmosphere. Once the space is evenly occupied, the molecules then show no tendency to unmix. Why not? Answer: because the 1g force that acts on all molecules in air at sea level is insufficient to overcome the kinetic forces due to collision between molecules. Put more simply - a molecule that gets a strong bump from below will be knocked upwards, against the weaker force of gravity.

What you are really interested in the density of the gas, rather than the weight.For most gases at atmospheric pressure, a given volume contains the same number of molecules at a given temperature. This is known as the ideal gas law. The density (or how "heavy") something is depends on the amount of mass per volume - a pound of lead and a pound of feathers has the same mass, but take up quite different volumes, and hence have quite different densities, with the leak having a high density (heavy) and the feathers having a low density (light). For an ideal gas, the density is just the molecular weight of the gas, divided by the volume of a given number of molecules. Since a given number of molecules always takes up the same volume for a gas, the higher the molecular weight, the "heavier" the gas is, or the higher the density. Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole ( a certain number of molecules). The oxygen in the air is actually O2, or molecular oxygen, with a molecular weight of 32. Hence, carbon dioxide has a higher density, or is heavier than oxygen. That is why you need to be careful with carbon dioxide. It can displace the oxygen in a room and lead to asphyxiation.

Since 1 mole of any gas occupies the same volume, you can decide this by comparing the molar masses directly.
Air is mainly nitogen [molar mass N2=28] and one fifth oxygen [molar mass 32], so molar mass for air will be around 29.
Molar mass CO2 is 44g/mole .. so it is denser than air. You can actually pour it like a liquid eg into a deepish container with lighted candles of various heights. The candles will go out in turn.

yes if the room is not ventilated.... let me explain it easier...
use this image to help you..

the after mixture is all gasses mixed together... careful now, not bonded together because they bump into each other causeing them to be spread together..... c02 next to 02 next to c02 not c02 next to c02 next to c02...... this means that yes there is c02 but its not created as quickly as the fAE we allow so while the mixture leaves your monotub more oxygen is being introduced into it. allowing the mixture to dilute into more 02. do you fallow?

Pour it in a monotub and watch what happens.....it will rise.....
But again, no one is talking about concentrated co2.
You are going off the deep end here.....

if its not ventillated of course im aware of this im just saying that if he puts the holes at the same level as the sub, its easier to get rid of the excess co2
