Hello:
I am wondering how the "mass reacted" is calculated. I am getting results that don't really make sense. I am guessing it has something to do with the way I wrote my treatment expressions.
Also, I am trying to express the nitrification process (assuming a 90% conversion of NH4+ to NO3-). I have defined the rain concen. of the NH4+ ("X"). In the subsequent layer, I want the converted concen. of the NH4+ (0.90*X) to be added to the rain concen. of NO3- (defined as "Y"). What is the best way to express this in a treatment expression?
Thanks,
Michelle
