I am looking for some quideline on how to determine a wind force on a rectangular object (like a highway sign) based on wind speed. I have managed to calculate the force using a fluids textbook but I'm not at all familiar with building codes and such so I don't know whether there is some...
I am trying to calculate a Reynolds number for a flat plate (20x15x1ft) in an air flow, in order to determine the drag force. The frontal area is 20x15ft. I don't understand which dimension to use for the characteristic length in the Reynolds number calculation. I think it is the dimension...
