WebPaschen’s Law predicts that for a given geometry, gases will break down above a particular voltage for a particular gas density; this implies that each gas has its own Paschen curve. Web24 Apr 2001 · Paschen's law ( V = f (pd)) should really be stated as V = f ( Nd) where N is the density of gas molecules, which is, of course, affected by the temperature as well as the pressure of the gas ( n/V = p/RT). An empirical formula for air (considering it as an ideal gas) is: x = 293 * p * d / (760 * T) Vbreakdown = 24.22 * x + 6.08 * SQRT (x) coreldraw cover page sample https://jocatling.com
