Hi, this is not a homework question. Been out of school for way to long and can't remember my physics. I am developing something and I need an equation. What is the angle at which liquid will pour out of a glass? The input I think would only be the % full the glass is. I do not think the size or shape of the glass would matter. The output would be the angle at which the glass must be tilted to start the output of water. Thoughts? Thanks!!
