By Spiral plate, do you mean helical type baffles? can you describe a spiral plate heat exchanger, and are you asking about the thermal analysis, or structural (stress) analysis as in TEMA?
you can try integrating with respect to y giving the area under the curve, right? while setting the limits properly. I'm sure you know shear stress = mu*(dV/dy)
also, this is homework
For a simple/rough and incompressible calculation using bernoullis principle:
http://en.wikipedia.org/wiki/Bernoulli%27s_principle
E.g. (v1^2)/2 + g*z1 + P1/p = (v2^2)/2 + g*z2 + P2/p
This obviously ignores the losses but gives an idea. Also, assuming your pouring to atmosphere and using...
Can treat it like a restriction orifice. It will consider the discharge coefficients depending on thickness, viscosity, temperatures, diameters, reynolds #, etc. to give more accurate #'s
The head pressure required might make your container quite high?
could try a belzona coating depending on what your doing

They are usually painted on smooth, but I can imagine you cant make it rougher when you apply it. Also expensive but good for temps up to 180°C
The actual heat transfer given out by your refrigeration unit will be different than your input power (10KW) if that's the case?. Even with insulation your gonna get some loss. I think the actual time to cool it down to steady state temperature wont be long given your power and convection.
Who is the target audience really? I have trouble understanding it, because I don't have the graduate mathematics to know the notations. All these shows that on youtube, news or Nova are interesting, but really, what are they trying to accomplish? I think it is only to gain public interest the...
Thin airfoil theory can give you analytical results:

of course this only applies to thin airfoils
your basically doing a charpy energy test. E.g. energy required to break the bolt. If you know what standard of bolts your using, e.g A193 B7, B8, etc, you can find the toughness requirements for those bolts. Impact energy is basically measured by experimental tests and is dependent on material...
ok, so once there done feeding, how are they releasing their mass energy?
would it be similar to a dying star? or supernova? there would have to be some fusion to release the energy in the event horizon and eventually become visible...otherwise there is no evaporation rate while its feeding
or...
If black holes exist, they cant consume infinite amount of matter, so where does this energy go if it is not dissipated?
Is it gamma ray bursts that dissipate this huge amount of energy?
Or maybe a better question is, once a black hole is created, how long can it last? or do they last forever?
you have 6 equations to work with. its not torque but a moment
sum of moments in the one direction equal zero. Should be solvable with only these. regardless of how many so called planar points your have
