The diameter of the chamber in my clothes dryer is about 2 feet, or 0.6 meters. The circumference is roughly 1.9 meters. Movement in there is pretty chaotic, but we can simplify things by assuming that items travel halfway around (from the bottom to the top) and then drop down to the bottom again. So, for one revolution an item will travel half the circumference plus the diameter. About 1.5m. When running, the dryer seems to do a revolution every two seconds. This works out to 42.6m a minute. A typical drying session lasts about 45 minutes, which means that items typically travel just over 2km – about 1.2 miles – while being dried.
This means my socks do most of their travel while I am not wearing them.
I could even this out by washing them less often, but this solution is unpopular with others. I could also balance things out by getting out more, but that solution is unpopular with me.
