Use of 'in which'

Question

Is the use of 'in which' correct in this context?
...and Fc is the flux vector:

where U is the velocity vector, ρ  the density, p the pressure, E the total energy, and Vc=V.n the contravariant velocity, in which
n is the unit normal vector to the face.
Thanks for your attention. I’m looking forward to your reply

I will not say it's perfectly correct. "In which" here refers to n ,for some extent it is understandable. But ,if you use ,where "n" is unit Normal vector to the face , would be correct.

This is an answer in which I invite you to consider the question and a parallel non-technical example.
The full equation is irrelevant to the question and the answer. The question relates to an expression,  U·n̂ , that contains symbols. Within the expression, each symbol has a meaning. “In which” refers the reader to the expression and the symbols that are within.
For the non-technical reader, consider the parallel example of the so-called Chinese curse "May you live in interesting times" in which “interesting" is a euphemism for “difficult”.
In conclusion, “In which” is clear, unambiguous and correct.

in which n is the unit normal vector to the face.

In = within.
Which -> the referent of which is U·n̂
