Vapour volume facts and questions

Post by pyrobrewer280 »

When water is vapourised, the vapour can be up to 1600 times (super heated steam) the original water volume. So for 1lt of water to be condensed from this vapour, up to 1600lts of vapour would travel up the column.

Questions

What is the ratio of the volume of 95% ethanol / water vapour @ 79C to 95%liquid
Does this reduction in volume cause a slight negitive pressure ( how much) at the condenser (drawing more vapour in)?
In areas of high humidity how much atmospheric vapour will also be condensed on the coil with an open top condensor (no i'm not sugesting we seal the coil, perhaps just a loose cover)?

In order to super heat steam or anything else you will need pressure. As in a closed system that is pressurised.

You will not have this environment in a properly constructed still.

The slight changes in pressure from entering the condensing area or related to atmospheric pressure differences are not major events that require prior planning.

In simple terms... DO NOT SEAL THE STILL.

The change in the amount of water vapour condensed at the top of a cooling coil due to a change in humidity is so small that IT JUST DON'T MATTER.

It is about the size of a gnat's butt that landed on an elephant.

The change in weight on the elephant don't matter. Not in calculus. Not in physics.

You will not be able to measure it with any tools available at a reasonable price.

Now...
What is the ratio of the volume of 95% ethanol / water vapour @ 79C to 95%liquid
Good question. I need a refresher on that one myself. Just to know the answer....

Real life answer... As long as my condenser knocks it down.... I gots distilled spirits. The energy involved comes into play here...

I hope that I do not sound smart a.... I appreciate your making me think.
I would rather teach a pig to sing than argue with an Idiot.
