Understanding Brun' Water

[p_p]

Edited out.
My question was about the inner workings of the calculator, thus slightly inappropriate. Didn't notice the copywrite notes.

Thanks anyway.

I think only one person could answer this question - the software author, Martin Brungard - you could try pm-ing him @ mabrungard

Comprehensive instructions and background water knowledge are in the spreadsheet (at least the paid version).

In the instructions tab, beginning with box 66, acids are discussed as they relate to their inputs.

Acids can be entered as percentage (titrated, stabilized as-purchased form), Normality or Molarity.

Within the program, pH is the output. Its change in value is related to the grain used, plus mineral and acid contributions. Relevant instructions begin in cell 53 through 99.
