A4,
The region of experimentation for two
factors are temperature (Levels of T set to:
100 ,200 and 300 °F) and catalyst feed rate
(Levels of C set to: 10,20 and 30 lb/h) . A
first order model in the usual coded
variables has been fit to a molecular weight
response, yielding the following model y
2000 + 1.5 x1 - 0.8 x2. Assume that the
change in the most relevant coded variable
is equal to one. The overall objective is
maximizing the response. Which is the
steepest ascent change for natural Variable
T?
