Dilute a Chlorine Solution: Dilution Law: V1*C1=V2*C2: V1=V2*C2/C1

eui DiluteSolution.ex <C1> <V2> <C2>
Usage:  eui DiluteSolution.ex <C1> <V2> <C2> <d>
eui DiluteSolution.ex <C1> <V2> <C2> <d> <adp>

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 <adp> is added to the
command line, the program will calculate a annual degraded C1
value based on the value of <adp>; Otherwise, the calculations
will be made based upon the nominal value for C1% at the time
of purchase.

option: <adp> allows the user to specify an annual degradation % other
than the default value of 20%. Enter as a whole number or decimal
fraction without the % symbol. Not Entering a value for <adp> or
entering 0 for the adp value will default the value to 20%

EXAMPLES:

To make 32 oz "Cleaner Bleach" with 2% Sodium Hypochlorite:
from stock Bleach with 6% nominal Sodium Hypochlorite:
eui DiluteSolution.ex 6 32 2
use 10.67 oz of C1 + 21.33 oz of distilled water to make solution V2 C2

To degrade C1 by 20% annual rate for 190 days:
eui DiluteSolution.ex 6 32 2 190  -- degrade C1 @ default 20% annual rate
Use 11.91 oz of C1 + 20.09 oz of (distilled) water to make solution V2 C2

To make 15 oz "Skin/Wound Wash" with 0.057% Sodium Hypochlorite
from stock Bleach with 6% nominal Sodium Hypochlorite:
eui DiluteSolution.ex 6 15 0.057 190  -- degrade C1 @ default 20% annual rate
use 0.16 oz of C1 + 14.84 oz of distilled water to make solution V2 C2

eui DiluteSolution.ex 6 15 0.057 190 35 -- degrade @35% annual rate
eui DiluteSolution.ex 6 15 0.057 190 .35 -- degrade @35% annual rate
Use 0.17 oz of C1 + 14.83 oz of (distilled) water to make solution V2 C2
