Figure 957. For Example 98 typical Glitsch Gempap preliminary design charts for structured packing. Note: These plots ate to be used in
carrying out the calculations described in the Glitsch bulletin. Graphic data presented hen? have been obtained in tests whose candtlons may
differ materially from your own. Curves on these pages are for Gernpak with crimp angles of 45" from the horizontal, and should be sufficient
for a preliminary review. The actual surface texture, which determines the final design, should be chosen in consultation with the Glitsch
process engineering std. Used by permission of Glitsch, Inc., Bul. 5140.
