Temperature/Flow Rate/Tube Length Effect on SO2 Permeation Tube Mass Loss
(with tube length => normalized tube length)
Jerry Mitchell / Stefan Leigh
2**3 FULL FACTORIAL DESIGN + REPLICATED CENTER POINTS
RESPONSE VARIABLE         = (normalized) SO2 Permeation Tube Mass Loss
NUMBER OF OBSERVATIONS    = 8 + 2 = 10
TOTAL NUMBER OF VARIABLES = 4
   RESPONSE VARIABLE = (normalized) SO2 Permeation Tube Mass Loss
   FACTOR 1 = Temperature            (2 levels--26.5 and 36.5)
   FACTOR 2 = Flow Rate              (2 levels--100 and 1000)
   FACTOR 3 = Normalized Tube Length (2 levels--10.2 and 20.9)

Note--2 "center points" were collected at (31.5,450,14.9)
      which corresponds to (0,-.22,0)
      The 2 measured values are y = .343 and y = .345
