Hi Jim,

Careful with those calculations, they might get you into Hot Water as the graphs indicate in the Engineer's Toolbox will attest.

[www.engineeringtoolbox.com]

I miscalculated the density of a cubic Ft. of water and just now corrected the value to 62.5 Lbs. Let's see, your calculation would give a density of Water at around 96*F, according to this chart's increments. Nice temp. for hot tubing this time of year anyhow. :) Just thought I would add to this post now that the figure of 1/2 62.5 at. 31.25 cube rt. = 3.149802625, still makes for an interesting Pi value very near to that of 3.15 value that Jacob uses quite often in his Polar Radius calculations derived from J.Michell's Canonical Model.

Best regards,

Stephen
