This may not be directly Chemical Engineering related but it is in a ChemEng course.
I am reading about transfer functions in a Process Control course and "nominal value" keeps showing up. Usually it is saying something like this: the bar over the symbol denotes a nominal steady state value.

Example: Steady state version of a CSTR balance:
0=w1*x1_bar + w2*x2 - w*x_bar
(x1 varies as x2 is constant)

x's are the fractions and w's are the flow rates. The flow rates are constant.

I am not sure if I need to give more information but let me know.

Thank you.

Also, my best guess is that they are the "best" values.

And just realised I meant to write "nominal" and not "nomnial".
