[QUOTE="perfor8, post: 4063972, member: 10088"] I'm not confusing pressure and compression. Water is compressible and compressed for industrial applications, and in nature. The water in your glass at dinner is compressed, due to it's own head (weight) and due to the weight of the atmosphere above it. It's not compressed much, but it's compressed. All matter compresses (occupies less volume) under pressure. Sorry to detract from the fella's water source issue thread, I'm just trying to elevate the conversation. People like to grab onto an idea, e.g. "water is incompressible" and lock that in as inviolable. That's admirable; I do it too. But like many things, it's more complicated than that. "Water is incompressible" is a generalization. For most common purposes, it can be considered incompressible, because it doesn't compress easily or a lot (relatively) and the compression can be ignored. Oh, and water isn't non-Newtonian, it's the quintessential Newtonian fluid. [MEDIA=youtube]pTYUpXLwMwc[/MEDIA] [/QUOTE]
