All the variables and constants in the equation are dimensionless.



Thank you!


How do I include 

on the same plot. Thanks!


I'll work with this.

Side question: How do I get to be good at using Maple?


It says:

Error, (in dsolve/numeric/process_input) indication of the unknown(s) of the problem {C} disagrees with input system {C(x)}



Is there only a numeric solution to this?

@Rouben Rostamian  

This is apparently what I have. Solve this (F and K are constants):

Boundary conditions:

What do you say?

@Rouben Rostamian  

I meant that the other boundary condition is:

DC(0)=F(C(x)-1); F is a constant by the way. for example F=2

The boundary condition is actually known as a Danckwerts type boundary condition

Any ideas on how to solve the problem using Maple? Thanks

@Preben Alsholm

Thanks to both of you (preben and carl).

I have the initial and boundary conditions. I'll take a look and get back to you.

@mehdi jafari ; @carl love

It works! I really appreciate your help, thank you!

@Preben Alsholm 

Thank you. This was helpful!

@Carl Love

Please find the attached file. Thank you very much. I am new to this, so if you can tell me a better way of solving this equation, please let me know.equation
