My son and I built a swim platform (raft) on a half dozen 55 gallon drums. I then made some 1 cf concrete anchors, which do nothing to hold the raft in a moderate wind. I have since learned that I need to account for the buoyancy of the concrete in water, but now I need to calculate the required weight of anchor to hold the raft in place in a 35 mph wind on an open lake at 6000 ft elevation.
What is the force that the wind exerts on a surface? I'll just assume a flat-sided raft and not worry about all the spaces between drums under the platform unless that would significantly change the results.
Simple units would be preferred (instead of things like Newtons, joules, pascals, etc.) because I'm old and my brain doesn't take to new units too well. Note: I'm still good with math, just not new units that I don't know how to convert.
