value fD is a drag coefficient for gas flow past inclined flat plates taken<br />
from Fig. 14-113, while U′g is the actual gas velocity, cm/s, which is<br />
related to the superficial gas velocity Ug by U′ g = Ug/cos θ. It must be<br />
noted that the angle of incidence θ for the second and successive rows<br />
of baffles is twice the angle of incidence for the first row. Most of<br />

Calvert’s work was with 30° baffles, but the method correlates well<br />
with other data on 45° baffles.<br />
The Karbate line separator (Fig. 14-110g) is composed of several<br />
layers of teardrop-shaped target rods of Karbate. A design flow constant<br />
K in Eq. (14-226) of 0.035 m/s (1.0 ft/s) is recommended by the<br />
