Dear members,
I have been playing around with PyNomo and it is a powerful product. By and large I have used it to recreate some simple nomographs that I have seen in text books that are too small or too aged to be of any use.
Now I am embarking on trying to create my own nomograph but I am having trouble deciding how to go about it.
The equation that I want to represent is as follows.
ln(C/C0) = 31000000 * exp(10161 / (T + 273.15) * exp (1.75 * pH) * d
Where,
C/C0  Final concentration / Initial concentration
T  Temperature, in deg C
pH  Solution pH
d  Duration, in days
Basically, given, T, pH, d and C, I want to be able to determine what initial concentration I will require.
Any assistance would be greatly appreciated.
Best regards
Andrew Lindsay

Re: Some ideas on representing an equation
Hello Andrew,
you have missed parentheses in your equation. If your equation is type
f1(C/C0)=f2(T)*f3(pH)*f4(d)
I would probably make it simple type 3 equation with logs. If the equation is not of that form, let's look it more detailed once equation is corrected.
