thanks for the replies. the university which i study at uses P&ID-100. @Don, thanks for the link. i did come across that before in my google search, however i was looking for something a much more extensive, a document which contained the symbols for a sensible heat storage bed, air heater...

To the viewer of this post, What is a good source for the symbols used in a P&ID? I would like to have a textbook or similar which would have all (if possible, or a majority) which I could easily reference to now and in the future when drawing/analysis P&ID's. Kind regards, pavadrin

does anybody know of a good program/software which flowcharts of a chemical plant can be made? one which includes the symbols etc.? many thanks, pavadrin

Not quite sure if this is the correct place to post this, but I am having difficulty converting between AE and SI units. Having grown up using only SI units, the AE units are a little confusing. What is the conversion formula for degrees Fahrenheit to degrees Celsius incorporating a degree...

Homework Statement a) Given the IUPAC name to the chemical formulas: {\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]^{2 + }} \left[ {CrC{l_3}{{\left( {N{H_3}} \right)}_3}} \right] {\left[ {Co{{\left( {N{O_2}} \right)}_6}} \right]^{3 - }} b) Give the metal oxidation state...

okay thank you for the reply

Homework Statement Calculate the pH after 24 mL of 1.00 M NaOH is added from the burette to a beaker containing 25.0 mL of 1.00 M HCl Homework Equations pH = -log [H+] 1*10^-14 = [H+][OH-] The Attempt at a Solution combined volume = 49mL n.unreacted(H+) = 0.025-0.024 = 0.001...

thanks, wealth of knowledge from this place is amazing

thank you, i have now solved the problem as i didn't quite understand what the problem was asking and i realized i have posted this in wrong section of the forum, sorry

The problem is as follows: Decide if the following pairs of orbitals overlap to form a σ bond, π bond, or no bond at all. Explain your reasoning in each case, including a sketch of the orbitals. Assume the bond lies along the z-axis. (a) 2pz and 2pz (b) 2py and 2px (c) sp3 and 2pz (d)...

Thanks for all the replies. Basically I need to replicate a rotation of >180 degrees, so maybe even a servo might work. How would I go about controlling a servo? The same way as a stepper motor? Thanks, pavadrin

PS: Not quite sure if it is the correct section of physics forums, if so sorry

To the viewer of this post, I wish to create a device which can replicate a rotation at point A at point B. What I was thinking was using a stepper motor to replicate the rotation at point B through the use of a controller and have some sort of mechanical-to-digital device which could incode...

hey if you host your image on imageshack.us and past the link into the forum, the image can be viewed in the post without the approval of the admin. not saying that the admin will block it, but it will allow the image to be viewed sooner if i see the image i may be able to help

Homework Statement The pressure in a volume of 1760 cubic inches needs to be raised from 16PSI to 40PSI. This is done via a second tank which has a maximum pressure of 100PSI. In order for this system to function, the second volume needs to be of a certain size. Calculate the volume required...
