    Carbon nanotube reinforced carbon fibre composites

    I was wondering if there was a definitive chart/data table with the properties of such a material. Many time has been spent looking through many papers, yet I am yet to find a table with for instance ... max tensile strength, max toughness, max conductivity I know there are many variations...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    btw, i don't suppose anyone has ever done a similar experiment, or knows where I can find the results of one online (i've done a bit of searching), just something to compare final results with :) thanks

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    thanks Out of interest, what is that the blockage actually does to affect motion? I am not questioning you (I'm no Ph.D. studentl!), but I presume the blockage is affecting some sort of flow in the fluid near the bottom of the tube when the ball is traveling down? Is the ball going to speed up...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    I will be honest and say a lot of he previous discussion (argument :D) was fairly confusing to me, although I get he general gist of it! So to confirm, the fact that the ball is blocking up 64% of the area of the tube is quite important, and I also understand the terminal velocity factor...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    Hi, I have completed the experiment, yet now trying to work out a decent viscosity is proving a nightmare, and using my calculator and also http://goo.gl/dt71T, my results for viscosity are always way off. Is there any chance anyone could look over these figures and help me work out which part...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    yeah I think so, the wiki formula is just a rearrangement of frictional force combined with the buoyant force balancing the gravitational force. To directly find the viscosity, I can just rearrange the wiki formula, pretty much just swapping the velocity and viscosity's 'position' in the...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    and sorry for not paying attention to your post, I read the first one and scrolled to reply, not seeing it! apologies!

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    ok, so the formulas on my previous post are just rearranged to give the wiki formula?

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    Hi everyone, thanks for your help! Using this document (http://www.engr.uky.edu/~egr101/ml/ML3.pdf ), on page 4 Fb+ Fd=mg where Fd= 6πμVd and where Fb= 4/3πr^3 × ρ ×g What are the units I need to use in the formula, as I have seen some densities with g/cm^3, kg/m^3, kg/cm^3 etc. Also...

    How Do You Calculate Fluid Viscosity with Stokes' Law and Variable Formulas?

    Hi, I am doing physics coursework on finding viscosity of fluids by dropping a marble into fluids, finding terminal velocity, then using stoke's law to find viscosity. (using density of fluid, sphere, sphere diameter etc). I have completed all the practical, now just the write up However ... I...
