## They are all dimensionless...

All the variables and constants in the equation are dimensionless.

@Kitonum

Thank you!

## One last help please...

How do I include

on the same plot. Thanks!

## Thanks Kitonum...

I'll work with this.

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

## Doesn't work...

It says:

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

## Only numeric solution?...

Thanks!

Is there only a numeric solution to this?

## Let rewrite the problem (now corrected)...

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

Boundary conditions:

What do you say?

## Danckwerts boundary condition...

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

## i have initial anb b. c....

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.

## Thank you so much, mendi and carl...

@mehdi jafari ; @carl love

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

## @Preben Alsholm  Thank you. This wa...

Thank you. This was helpful!
