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...

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...
Homework Statement
So my friend asked me for help because he assumed having a math degree meant I knew math :rolleyes:

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...
For a project/idea I'm working on, I need to find the charge density of tap water. I've read that this can be determined by simply subtracting total protons minus total electrons. I've got a list of elements that are in the water, but I'm not 100% sure how to find the exact number of electrons...
So I've read through https://www.physicsforums.com/showthread.php?t=32409" thread on valence electrons but it doesn't really answer my question. I think I am in the right forum, I was debating between here and chemistry but it deals more with atoms. What I want to know is this:
How do I...
I'm working on a design for a certain kind of generator. My main issue is that based on how the generator works and the circumstances in which I am designing it for, I end up with the problem of having very little voltage but a whole lot of amps. My theoretical/ideal voltage is .065v, and my...
Alright, I'm working on an idea for a MHD generator, and I have a water based solution. That is
Cl- 6250 mg/L or 176 mmol/L
SO4^2- 6250 mg/L or 65 mmol/L
Na+ 6250 mg/L or 272 mmol/L
K+ 6250 mg/L or 160 mmol/L
Ca^2+ 5000 mg/L or 125 mmol/L
If I'm doing my math right, that means my...
So it has always been my understanding that in order for something to electrically conductive it has to have more electrons than it needs. If the electrons can be easily shaken from their atoms, then it's conductive. The easier it is for the electron to move to the next atom the more conductive...
Leaving the physics out of this, I'm working on an idea for an in home MHD generator. I'm trying to figure out a conductive fluid to use. I'm back to the idea of salt water, or H20 + NaCl. I know this is a very conductive solution, but I'm no chemist. What I plan to do is put a MHD generator and...
I'm working on a project and right now my idea fluid is to use Gallium, a liquid metal. Only major issue is its currently about $1000 USD for 1kg of this stuff!So I can't afford gallium. Mercury isn't that cheap either and its a bit dangerous if not handled properly.
What about other fluids...

I'm going to be entering into that (^^^) competition with one other person. We are going to be doing it on an MHD generator and its use for automotive transportation and as a home generator, amoung other uses.
We are just...
So I'm trying to get my fm circuit to work. I've taken the design from the website below.
