You'll want to dip your pan in the water after it's filled up and swirl it around in a clockwise motion. This will help settle the gold to the bottom of the pan, since it is a heavier sediment, and the motion of the stream will help wash the lighter sediments away. You want to try to remove everything except the gold nuggets and flakes, so ...

Figure 1 shows the dimensions of the tunnel; the square cross-section means that the depth dimensions are identical to the heights. It is built of 5mm Plexiglass plates glued together using methylene chloride. The pressure difference in each part of the tunnel is registered by the heights of ink in tubes (5mm bore) that are linked by vinyl ...
Here is a wind tunnel design that was developed at NASA Glenn during the Centennial of Flight Celebration in 2003.

The Argo served these mines by draining hazardous floodwaters and transporting ore turning risky operations into lucrative honeypots. Two mines in particular, the Sun & Moon and Frontenac, played a large role in The Argo Tunnel's chosen location.
1. Start by selecting a wind tunnel. 2. Next, set a limit on blockage ratio (typically 5% is as high as you will want to go). Then determine a maximum allowable size from this limit. Either your wing chord, cylinder diameter, or whatever other value you are using for your Reynolds number reference length. 3.
