Hi, I need to make a simple and cheap device that I can water droplet at a constant rate (from a bucket of water). The size of the droplet doesn't matter, it just needs to be dropping at a constant rate (at least for a day). So I was thinking, can I acheive that by putting half of a cloth in the bucket, and the other half on the outside of the bucket. By doing that, the water should be sucked out of water because of diffusion, and the outside half of the cloth will be dropping water droplet at a constant rate. Will this work? Is ther any other way I can make a device that can drop water droplet at a constant rate (at least for a day)? Is is there data out there that can help me with the diffusion rate for certain type of material? Thank you very much!
