SUMMARY

The discussion centers on the feasibility of pumping glycol fog through a 3/4" pipe without it reconstituting into liquid form. Participants emphasize that while fog consists of tiny liquid droplets suspended in gas, using larger pipes (3"-6") is recommended to minimize condensation. The consensus indicates that a smaller diameter pipe, such as 3/4", may lead to significant condensation issues, potentially causing leaks or clogs. Ultimately, utilizing larger pipes is advised for effective fog dispersion over long distances.

PREREQUISITES
  • Understanding of glycol fog properties and behavior
  • Knowledge of fluid dynamics and pressure systems
  • Familiarity with ductwork design and sizing
  • Experience with fog machines and their operation
NEXT STEPS
  • Research the impact of pipe diameter on vapor flow and condensation
  • Learn about glycol fog machine specifications and recommendations
  • Investigate fluid dynamics principles related to gas and liquid mixtures
  • Explore ductwork design best practices for fog dispersion
USEFUL FOR

This discussion is beneficial for event planners, special effects technicians, and engineers involved in fog machine operations and design, particularly those looking to optimize glycol fog distribution in large setups.

Is it possible to pump glycol fog through a 3/4" pipe without it reconstituting into liquid?
 
Physics news on Phys.org
Why would it become liquid ?
BTW fog is already liquid ... just an accumulation of tiny droplets in a gas.
The droplets are so small that the hole pretty much doesn't matter.
 
I have read on several fog machine websites that they recommend transferring the fog through a 3"-6" duct to keep the fog from recondensing into its liquid form again. I'm intending on pressurizing several hundred feet of 3/4" pipe with a glycol fog and have it coming out of several small outlets throughout the line.
 
Wait.
If you are talking about glycol vapor being pumped through the pipes, the bigger pipe will have an advantage.
The bigger the pipe, the less vapor would condense prematurely in the pipes before coming out.
Sadly, but I don't really have a clue how you would figure out mathematically how big of a difference it would make.
Having a pipe with a four or more times lower radius will significantly influence the flow and condensation in the pipe.
Sadly, I cannot really tell whether it would still work. My guess is yes, but you would have quite a bit of condensation in the pipes which could be a problem.
They might leak glycol or clog the flow or something.One thing is for certain: you wouldn't get as much fog out one side as you put in the other.
The people who write the websites you read through will have some experience with this, so if you are going to do it right maybe take the bigger pipes(they probably know what they are talking about).
30 meters of pipe doesn't sound like a little garage project :wink:
