The discharge end extends with a straight parallel nozzle outlet for a distance of 0.0311 inch (0.787 mm). The discharge outlet of the nozzle is spaced rearwardly from the leading face of the aircap (0.1533 mm), and a central aperture is chamfered toward the leading face of the aircap and has an axial depth of 0.021 inches (0.533 mm).
