Thoughts on spark length and the "Freau Equation"
Original poster: "Jim Lux by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jimlux-at-earthlink-dot-net>
I would assume that the equation proposed by John Freau for predicting max
spark length (=1.7 *sqrt(VA)) is based on 120 pulses per second. That is,
it's really more of (length in inches)= 1.7 * sqrt(120 * energy per bang) =
18.6*sqrt(energy per bang in Joules).
Obviously, there are breakrate effects on spark length, but, for rates in
the 100-200 bps range....
