non-dimensionalisation

[ol98]

I've got to non-dimensionalise the differential questions

By letting:
N=N0n
C=C0c
t=t0T

I managed to get the dc/dT equation by the following:



However I'm struggling with the dn/dT equation.

As far I've got to


It's just getting the left hand side of the equation correct, any help would be really useful, cheers

You need to define your variables carefully!! What is the difference between "t" and "T"? What is the difference between "c" and "C"?

It's t=t(subscript 0) tao
and C= C(subscript 0)c

if that's what you mean?
