Weight belt equation

[Bubble Blower 479]

Um, glbirch, I'm quite familiar with "Harris" Taylor's altitude correction paper, and I'd like to quietly point out that he does not subscribe to this fablulous compressibility of water effect (which is perhaps limited to areas of Texas?). Taylor's paper just shows how to correct depth readings from a gauge calibrated to display fsw below mean sea level - when the gauge is used at higher altitudes and in fresh water.

I used his examples to put together a correction table for diving some of our Oregon lakes, and then took my gauge down and compared it to a marked line and to the table.

So, no offense meant, but please understand that Taylor's no internet looney.

This sure fits what I learned in my physics classes for my degrees. 1 Atm is defined by the column of air above your location and varies from one location to the next. That would change the depth to reach the second atm. The unit of 1 atmosphere is only fixed when you also state the STP (Standared Temp. and Pressure). Sea level is used as a standard of 14.7 psi =1 atm. When you leave sea level then your use of "atmosphere" is no longer 14.7 psi.
