Would a 125 watt volume air pump be powerfull enough to do this trick?
I thought i'd build something like this on the basement floor and thus absorbing as much coolness as it can while the attached air volume pump circulates air through the tubing from and to the livingroom above.
The question i have is:
Does a volume air pump have enough power to push air into 20 meters of hose?
I consider using a compressor but it makes a terrible noise and probably does only a few liters per minute.
