Well in most cases, the base circle is larger than the dedendum circle in diagrams I have seen:

Either way, what I am understanding is that it doesn't matter? Like the involute line starts from the base circle but it doesn't matter...
Hey guys,
Trying to design a spur gear but I am very confused as the root circle/dedendum ends up being greater than the base circle. What do I do in this case? The gear I'm trying to design has a 68.33mm pitch diameter, 60 teeth, the pressure angle a standard 20 degrees. What am I doing...
Right, but conventional 2.3v supercapacitors are single cells rather than two in series as I understand. I don't get how that works. I also understand how this can easily be explained by adding the voltages per electrode, but even then the potential difference would be greater than 1.48v...
I understand. Now how do make that work in a supercapacitor? If you read the instructions to build one I've provided, you have the basic design of a supercapacitor with two electrodes. According two what your picking from the wiki passage, that designed capacitor should also function at 2.3v...
Actually I was just coming across this: http://diygadgets.co.za/diy-supercapacitor-home-made-super-battery/
Basically this is instructions to make a supercapacitor using an aqueous electrolyte and it too operates only below 1.2 volts. This bodes the question for how do commercially available...
Regular supercapacitors use KOH as their electrolyte. That has higher conductivity than NaCl solution. For a supercapacitor, the electrolyte must be ionically conductive and not conduct the electrons from the anode to the cathode and thus maintaining charge separation. I think really my...
Hey guys,
Currently I am trying to build a low tech super capacitor based on the working the principle. Right now I am using a single beaker with two aluminium foil positive and negative electrodes with an electrolyte of 6M NaCl solution. The power source is a new-ish triple-A battery running...
Hey guys,
I was trying to find the answer to this question but could not seem to find anything. I am trying to figure out how to calculate heat transfer rate between a liquid and a gas. Say the the liquid is water in a chamber (with no heat transfer to the walls). The gas is the residual...
