How does water escape the pot?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of water escaping a pot through a nylon scrubber, which acts as a wick siphon. As the pot fills, water overflows, but a steady stream continues to flow from the scrubber due to surface tension effects. The water level stabilizes approximately 20mm below the pot's edge, correlating with the scrubber's position. This illustrates the principles of capillary action and surface tension in fluid dynamics.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Knowledge of capillary action
  • Familiarity with surface tension concepts
  • Basic physics of siphoning mechanisms
NEXT STEPS
  • Research the principles of capillary action in liquids
  • Explore the effects of surface tension on fluid behavior
  • Study siphoning techniques and their applications
  • Investigate mathematical models for calculating surface tension
USEFUL FOR

Students of physics, educators explaining fluid dynamics, and anyone interested in the practical applications of capillary action and surface tension in everyday scenarios.

I was cleaning up the kitchen, and there was a large pot that had been filled with water to soak in the sink. A rectangular nylon pot scrubber was hanging over the side of the pot, about 2/3 in the pot and 1/3 hanging out.

As I ran the tap, the pot filled up and overflowed, but even after the water had levelled out a steady stream of water continued to flow from the outside corner of the pot-scrubber. Eventually, the stream slowed, then became a steady drip, and after several minutes it completely stopped, by which time the water level in the pot was around 20mm below the top edge, and roughly level with the corner of the pot scrubber from where the water had been dripping.

So, I have two questions...
  1. How does this work?
  2. How do I explain to my wife why I haven't finished cleaning the kitchen?

interesting - so a syphon without a tube? where the surface tension is the tube? I wonder if you could calculate the surface tension based on the final water level?
