OG Complex Work Unit Math
which comprises the following parameters:
ρG is density of the transport gas at 20° C. [kg/m3];
νG is flow speed of the gas or compressed-air quantity fed to the distributor device [m/s], measured in accordance with ASTM D3154-14;
VDM is volume flow of the sealant quantity fed to the distributor device [m3/s], measured in accordance with ISO 1217, annex C;
D is diameter of the feed openings [m];
γDM is surface tension of the sealant at 20° C. and normal pressure [kg/s2] measured in accordance with ASTM D1331-14 (method A); and,
a is the number of feed openings.
