UDC 537.523

Experimental results are generalized and a formula 
for the velocity of arc motion in a variable-density medium in the 
annular gap between the coaxial electrodes of an electric-arc gas 
heater is refined based on consideration of the balance of the Ampere 
motive force and the force of aerodynamic resistance that affect the 
arc column.
