Subject: Re: Coyote Wind Block Calcs / Fishermans Park

I found another interesting item in the Coyote RDEIR report (page 39):

  "The adjustable ceiling and turbulence generators allow speeds
  within the tunnel to vary from 1 meter per second (m/s) to 8 m/s,
  or 2.2 to 17.9 mph."

17.9 mph? What's up with that?

If wind tunnel speed is equivalent to real world wind speed, then the
study is flawed - it ignores the wind speeds that define shortboard
sailing, which was the whole point of the study.

Brad, can you find out from your CE bud if 18mph in the tunnel is
equal to 18mph in the real world, or is there some standard scaling
factor (due to air viscosity or something)?

Thanks,

  - Matt
