will a large capictator split water i a second?
Posted 4 March 2011 - 05:26 PM
ok for a physics project i have to design a launcher that gets all power from a 1 farad capictator at 13.8 volts. i want to know if the capictatior can split a ml of water into oxygen and hydrogen gas and the ignite the whole messs again? any help would be much appreciated.
ok i did the energy conversion for the capictator and i get 95.22 joules and if the system was 100% efficent then it would take 121 joules to split a ml so atr most i could split .5 ml of water but would the explosion be enough to propell a .25 inch by .5 inch rod?

A mole of hydrogen will give 18 ml of water so each ml will need about 17KJ
Your 95J will split about 0.006 ml. You seem to have miscalculated something.
It gets worse.
The capacitor has a charge of 13.8 Coulombs; that's enough electrons to neutralise the charge on about .00015 moles of H+ ions and will generate half that many moles of H2. In doing so it will split just 0.0013 ml of water and form about 3 ml of gas.
As for "would the explosion be enough to propell a .25 inch by .5 inch rod? "
Well, not very far.

A solenoid may be a simple way to use the same concept, although you'll be accelerating more mass.
I don't believe in free will, but I choose to pretend it exists.

i can't find anything on-line about coil geometry other than trial and error and think that there has to be a better way to accomplish this.
Go take a look at this site
lots of other links there, including THIS one : [url]http://www.instructables.com/id/The-0-Coil-Gun/[/url]
