I am working on a project, all details can be found http://www.overclockers.com/forums/showthread.php?t=680115" is the catalog page with the options. I've googled about annealed and "dead soft" however I still can't tell exactly how soft/flexible it is. All I need it to support is water running...

We have a fisher scientific locally, but they want $40+ for 100-300g of magnesium.
An idea I was told about was to use magnesium oxide, which you can get from any nutrition place, such as a GNC. Mix it with hydocloric acid, to form MgCl + H20, then use electrolysis with carbon electrodes, to...
Hey guys,
I'm on a bit of a time crunch here, I have to have everything buy Wednesday (10/27). I've been asked to give a presentation on food in the classroom at a meeting on Wednesday. What I normally like to do is a demonstration involving a Flameless heater. I just use the same technique...
Ah ok, I see.
Now I get \frac{-1}{4}\frac{d^2y}{dt^2} = -4y
\frac{-1}{4}\frac{d^2y}{dt^2} +4y = 0
so,
\frac{-1}{4}r^2 + 4y = 0
y(t) = C1 e^(4t) + C2e^(-4t)
Now doing the same for x(t), I end up with the same equation of
x(t) = C1 e^(4t) + C2e^(-4t),
however given my initial...
Homework Statement
So my friend asked me for help because he assumed having a math degree meant I knew math :rolleyes:

Convert this system to a second...
Yes and no. You are talking about MHD propulsion, while I am talking about a generator to produce electricity. Same principles, but by no means do I supply the amps. The amps are created by the flow/movement of the fluid. Not the movement by the amps (which is what you are talking about). When...
Interesting, thanks for the link, it's quite detailed so I'm going to take my time reading through it.
I guess I should explain to you exactly what I'm trying to figure out. What I want is to find the amperage of a flowing fluid. As long as there is a net charge in said fluid, and the fluid is...
Yes those are the units (expect I'm using meter not cm, but that's not overly important).
For the fluid, seawater, brack/brine water, tap water. I guess maybe it's not as generic as I though, in terms of the equation and charge density in general. I'm looking at liquids specifically.
I need to find amps, so it's really all or nothing for that equation. Without the charge density, I'm left with Coulomb * m2 * m/s = Coulomb m3/s or Amp * m3. I need the charge density.
As for the fluid, well I'm looking for how to find the change density for generic purposes. I don't have a...
How would one determine the charge density of a fluid?
I'm using the equation of I = qnvA . Amperes = charge of electron * charge density * velocity * Area. The only thing I'm not sure of is how to determine charge density. I've read several websites and I have a few textbooks here...
I got it from a textbook I have. The section talks about tachmen and uses a Tortoises-Hares fable to explain it. Really crummy section, the rest of the book is okay. So I was just going off of the one sentence I quoted below...
