(A-1) Consistent
(A-2) PC5 by CV6 only
(A-3) FC by CV6, CV7 or CV8
(A-4) PC4 by CV5, CV6, CV7 or CV8

(B-1) Consistent
(B-2) PC5 by CV6 only
(B-3) FC by CV2, CV9 or CV10
(B-4) PC4 by CV2, CV5, CV6, CV9 or CV10

One can find out right answers by reasonable process insights (or
consistency rules) by recognizing W3=W1.

Another way of approach is to rely on mathematical handling of steady-state
process models as shown at the center of the sheet.
      The math formulae are just a set of material balances and pressure
balances at each CV @steady-state condition.
      (thirteen(13) equations and thirteen(13) unknowns)

The free math handling software "MAXIMA" will readily and instantly return
the Causes-and-Effects relationships between the given conditions and
unknown conditions.

see pdf-file!

The inputs and outputs of "MAXIMA" are cited and listed at the center of
the sheet, and these outputs indicate the complete answers to those
questions above.
For example, the output of "p5=(w1+cv6*pd)/cv6" means that CV6 among other
CVs is the only CV which affects P5.

"Which given conditions would affect which conditions @SS" is the central
issues of consistency rules of plantwide control configuration !
