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)
