Hello Simon,
Thank you very much for your response.
Maybe I am not fully understanding your answer.
The A, I am trying to find is not the surface area of the sphere but rather a constant found in the solution to
dm/dt = -c*s(m) = -c*4πi*(3m/(4πi*ρ)^(2/3) (equation 1)
where the solution to...
Hello All
I could get some help I would greatly appreciate it.
I am trying to figure how to calculate the dissolution time of sphere undergoing constant corrosion at a rate
of corrosion.
Through a little google-fu, I found an article which gives me the solution (...
Hello Everybody,
I would greatly appreciated your help. I have been working this problems for the past couple hours and can't seem to find the answer. I tried Google, and opening up my old textbooks but to no avail. I could really use some help.
I have sample of tungsten coated...
Thank you ever much for the reply physics girl phd. You have helped me avoid several errors in witting my letter. Thank you again. I am off to write that letter.
ps. I have one more questions if you have time to answer it. Growing up I have severe learning disabilities, to the point where...
Thanks for the advice. Thank you for being completely honest. Do you think I have a chance if I can do well on my GRE's. Do you have any other recommendations on UC schools that have a good materials program that i might be able to get into. I think my GPA, being only 3.21 will hinder me from...
Not sure if this question belongs here, but i have a question about getting into one of the following, UCSB, UCSD, UCB, or cal tech. My first choice would be UCSB.
I am currently and mechanical engineering major at sdsu. My cumulative GPA is 3.21, I am in tau beta pi (the honors society), am...
Hello Every one,
I am trying to design water vessel which shaped like an inverted house (i.e. a rectangle attached to a triangle). I want to find the pressure and force distribution along the walls of tank (it is open to atmosphere). I have tried solving this in excel using the equation...
Ok thanks for the help. I am having a problem find the currect solutions to this problem, from a previous post of PF https://www.physicsforums.com/archive/index.php/t-204570.html
i found that u(r,z) = u_0 \cdot \sum_{n=1}^{\infty}\frac{sinh(\lambda_n z) \cdot J_0(\lambda_n r)}{\lambda_n...
ok thank you very much for the reply. I looked up the conduction equation for spherical eq and got. Can u understand this, i don't really known how to work with latex, but i can reenter it needed.
1/r(d/dr)(kr(dT/dr)) + 1/r^2(d/dO)(k(dT/dO) + d/dz(kdT/dz) + q = pc(dT/dt)
once again the...
I know my last post was a little long winded, but i here a summary of my problem. I have to use separation of variables to find the Tx in a cylinder which is heated from the a whole along its axis and the out side of the cylinder is completely insulated.
In class we look at bessel function...

Could some one please help me. My professor for a lower level programming class (in labview) has given the class the following assignment. This is not a heat transfer class and he has not spoken/taugh us anything related to heat transfer. He emailed us a few pages from a heat transfer...
Labview help!
Hello, everybody. I am not sure if this is the right spot for my question because labview is a ME not CS
Does anyone have any good recomdations of books or online tutorial which can help me learn this software. I am currently taking a class in it, but the class has no text...
