Attachment 1 - Flow and honeycomb diagram.pdf

This is a technical diagram showing the design specifications for flow straighteners and honeycomb sections in what appears to be a large water channel testing facility. The first page shows a side-view schematic of the entire channel system that is 73m (240 ft) long and 20m (65 ft) high, with key components including a pump, diffuser, test section (13m/43 ft long), and a 6:1 contraction section containing the flow straightener and honeycomb components.

The second page provides detailed specifications of the flow straightener and honeycomb sections, showing both front and side views. The flow straightener section consists of sixteen rows of 4"x4" square tubes that are 2' deep, while the honeycomb section contains approximately 50,000 2" wide tubes that are 1'7" deep. Both sections measure 5' x 5' overall, with a small air gap between them. The diagram includes precise measurements and layout details that would be necessary for maintenance or replacement of these components.
