Hello all,I'm in need to design a solution to prevent existing concrete surface to collect ice, when there is sparklingwater flying around. This is actually dam and the surfaces are the sides of it and dam is slightly leaking oropened to let water run, so that there is lot of water drops everywhere.Now I got idea to clean these concrete surfaces by high pressure water jets, glue RST-plate stripes side by side using epoxy, and finally connect these plate to electric system to warm them max up to 30 deg. Celsius and surrounding climate is below Zero.The total area in question is ca. 30m2 per one dam and I have three dams.My question is how to calculate the thickness of the plate, if they are f.ex. width=200 and length 5000 and what kind of current it might need??Better off, if someone can give formula where these values could be calculated by myself?  ;>)Best Regards Matti Pitkanenwww.pcskouvola.fi

This is Rev 1 with a correction on Example 1, minor typo error.Plus a short history on Mr Laplace and Mr Heaviside.Physics students if did not get it let me know.Sincerely,Karl (Kosmas)

Hi All,Laplace Transforms Prime file with notes.Tutorial with worked examples.If any of the Physics group students did NOT get his I would have to post it per community.I don't know how it would get to all if Its uploaded for one community. Cheers and Thanks.Karl Bogha.

As it can be seen in the attached picture, I need to find an equation to fit this curve if I have only the data from the picture. Since this is a graphical method, I can't have a high accuracy but I need a generalized function that would give me the value for every point. As you can see, the values in Y-axis are not linear so I have no idea about the type of the function.

I use tables quite a bit but when I used them as input to calculations, the output does not reflect the number of data points that are supposed to be calculated from the input data.See example below (only one value for chargeVolume). What the heck is happening or I am brain dead for this simple calculation.

I just had an Error. Suddenly I couldn't use operations like the derivative. There is now just the notice: unknown_outofproc_symbolic_engine_failure.

Can I import a CREO Model into Mathcad directly; and, if so, how can Mathcad help us to improve our design?

Is this possible?RegardsErlend

Dear all,I would to create a calculation sheet in Mathcad 15 where when I select an option the reference value are automatically selected.For example:In the previous table I would select the value determined by weld condition (full penetration) and quality level 2.I would to create  a windows that, when I select this two condition, the referring value is automatically selected.Best regardsStefano

   Hello Everyone, What does _mult mean and how dose it work ?     Thanks in advance for your time and help.           Best Regards.

I have attached a pdf file with an explanation of what I am trying to accomplish.  The Mathcad file attached can be edited as needed.

I'm using Mathcad prime 3.1 express at my school for electrical calculations.And I am constantly switching between the taps  "MATH" and "Math formatting"It's really a hazzle..Things i would like to change isGeneral should be Decimal or Engineering, Decimal values i need to be (5) not (3) as it is now.and finally complex numbers should be displayed in polar instead.I find myself switching the tab almost after each line of writing, and for one assignment i usually fill 2-3 A4 pages.so it's really getting to me that i can't figure out how to set these things so they STAY that way be default.Anyone have an idea on how to change the standard values under math formatting?

Hello, anyone knows how to change the background color of mathcad prime 3.0 sheet.thanks in advance for your help.

Hello,I have followed the set up instructions for the ODBCread and ODBCwrite custom functions (copying dll, dbread, and dbwrite files to the Custom Function folder) and I get the following error:Is there something I'm doing wrong or is there a solution for this?Thanks,Adrian

A colleague uses a seat of MC14 from XP (possibly WIN7) 32bit, but now had to move to WIN8 64bit. MC14 installation issues occurred. Is MC14 possible on WIN8? I welcome suggestions/recommendations.Sincerely,Norm

Hello,I hope, this is the right thread.Could someone explain me, what I have to do with this loop.I want to get F as a (3,4) Matrix.Thank you for helping ...

Dear all,How can I set this programming function in mathcad 15?RegardsStefano

Bonjour, Je voudrais savoir si la notation instaurée par le physicien Paul Dirac, notation qui est communément utilisée en mécanique quantique, est disponible dans une des nombreuses versions existantes de Mathcad et, si oui , laquelle ?Merci d'avance et meilleures salutations,Jean Fraiture

Hello,i want to calculate following filter in series:LC+RC+LCspice simulation result:with following transfer functions:filter1:filter2:filter3:Could i multiply all three transfer functions in laplace?As result i get a different magnitude like in spice simulation. Could it be that transfer function of all in series shall calculate in a different way?Second Question: How can i display the phase without overdue of 180° in the diagram?Thanks in advance.Michel

  Hello Everyone,  The question is : Is there a reason Mathcad 14 doesn't accept (3) ?       Thanks in advance for your time and help.             Regards.

How do I  FIND and REPLACE in prime 3.1  (What are the key strokes?). I want to use find and replace variables in Prime. Where is this functionality?

I've noticed this several times.  I have to assume it's a bug.When using symbolics to solve for a variable, Prime 3.1 swaps out my defined variable with the built-in variable.  In this case, gamma (ratio of specific heats) is replaced with Euler's constant.  The good news is the color of the variable changes so I've at least got a clue it's happening.  But it shouldn't happen, right?  In this case it's unitless (or units cancel) so I didn't even get crazy units to point out a problem.  Is there a modifier to prevent this? And it brings up another question, is there a way to turn off built-in constants?  (except for pi and e, ideally)  While I understand they are useful, on several occasions I've gotten 'wrong' answers because of a mixup.  (e.g. sigma = Stefan-Boltzman instead of stress).  Admittedly my fault but I'd rather get an error if I haven't defined 'h' rather than it jumping to Planck's constant.  When trying to advocate fo
