| Apr 16, 2011 at 3:34 | comment | added | Spatula City | @nibot: No problem, but I won't explain it directly -- it's good to ask questions like that when you don't know, much better than posturing like you do. Try googling something like "Visio valve schematic" or "pipe systems schematic symbols". And do let us know what you find! | |

I have learned more about this.

| Apr 13, 2011 at 2:55 | comment | added | nibot | I suspect, like @mmc mentions, that, in the approximation you describe, you could write this as a system of linear equations. | |
| Apr 13, 2011 at 2:49 | comment | added | nibot | Pardon the naive question, but could you explain the various symbols in the diagram? The tanks are obvious enough. I assume the two-triangles thing is a valve. What about the two little circles with lines through them? And the triangle of horizontal lines (looks like an electrical ground symbol)? Also, what is the action of a valve? Does it limit the rate of flow to a fixed value, or just present a fixed aperture, or ...? | |
| Apr 13, 2011 at 2:22 | comment | added | mmc | @Ben Phillips Have you thought of transforming your problem to an electric circuit? Your simplified behavior seems amenable to an electrical analogy (bomb -> source, pipe -> resistor, tank -> capacitor, ...). | |

| Apr 10, 2011 at 21:08 | comment | added | Spatula City | It is not stationary, but if I could at least get a stationary model working correctly, I would be much better off than I am right now. I think I could add in special conditions to get a non-stationary system modeled fairly correctly. | |
| Apr 10, 2011 at 20:52 | comment | added | Marek | 60 oz beer sounds like a fine bounty to me :) Just to make it clear (sorry if I am blind): is your situation stationary (i.e. with constant flows) or not (due to finite amount of water in those tanks)? | |
| Apr 10, 2011 at 20:51 | comment | added | dmckee --- ex-moderator kitten | You keep running into horrendous difficulty because the full problem is one of the touchstone "hard" problems in physics (and for that matter in computational methods). Its not my field, but I know a few people who are in it. I don't think they ever use a system as simple as you describe. | |
