Attached is a picture of the object that I am trying to figure out the forces due to currents that will be acted on it.(adsbygoogle = window.adsbygoogle || []).push({});

Here are the questions I have ( I really just need some direction in the area of appropriate formulas)

1) what are the force againts the surface of the collector in foot pounds and pounds per square inches(umbrella looking part) when the angle at the base is 20 and 30 degrees and the total diameter is is 20', 30' 40', 50', and 60' at a current flow rate of 5 mph, 7mph, and 15, mph

2) Based on the above information what is the anchor weight if there are 4, 6 and 8 anchors deployed to keep it at a stable position for the various degress of the octogon (shape of the collector) and is position important.

I appreciate any help. I have not taken a class fluid mechanics and from everything I have read on the internet shear stress seems really important and I could be wrong but it seems that it will be the majority of the forces acting on it by a current.

Thanks
