This is dataplot data file boxreactor_5_8.dat Chemical Reactor 2**(5-2) (k=5,n=8)
Feed rate/cat/ag rate/temp/conc effect on chemical reactor efficiency
Box, Hunter & Hunter (1978)
Statistic for Experimenters
Wiley, page 379 and 377
2**(5-2) fractional factorial design
Number of observations = 8
Total number of variables per line image = 7
Response variable = % reacted
Factor 1 = feed rate (2 levels-- 10 & 15 lit/min)
Factor 2 = catalyst (2 levels-- 1 & 2 %)
Factor 3 = agitation rate (2 levels--100 & 120 rpm)
Factor 4 = temperature (2 levels--140 & 180 deg c)
Factor 5 = concentration (2 levels-- 3 & 6 %)
