Ok, I promise I will not post anymore dilution code. Honest!

-- -- DiluteSolution.ex -- include std/console.e include std/math.e include std/convert.e constant Usage = sprintf("%s", { """ Dilute a Chlorine Solution: Dilution Law: V1*C1=V2*C2: V1=V2*C2/C1 Usage: eui DiluteSolution.ex <C1> <V2> <C2> eui DiluteSolution.ex <C1> <V2> <C2> <d> C1 = % Sodium Hypochlorite of stock Bleach at time of purchase V2 = target volume of solution to create with C2% Sodium Hypochlorite option: <d> is the number of days since purchase of C1 + perhaps an estimate of shelf days prior to purchase. If d is added to the command line, the program will calculate a degraded C1 value based on a 20% annual rate of degradation. Otherwise, the calculations will be made based on the nominal value for C1% at the time of purchase.
