Abstract

A ballistic piston apparatus is described briefly. The instruments in the apparatus and the associated external measuring circuits are discussed in detail. The differential equations which describe the energy and material transport in the axially-collapsing cylindrical sample-gas chamber are derived and solved numerically. Compressibility factors are calculated for nitrogen gas employing data obtained from two tests made on the ballistic piston apparatus. Temperatures in this investigation range from 2300° to 3300° R, and pressures from 1000 to 6300 pounds per square inch absolute.
