The results for a curve measured at 300 rpm and 3,000 rpm of the final steps of the sensitivity analysis: Finding the combination of W and wac that result in the least variable results for the cathodic Tafel slope. (a) The mean and standard deviation of the variability as a function of wac, evaluated for each value of W (σW(wac)). The star represents the variability when no weight distribution is applied. (b) The varibility as a function of wac, for the selected W, that results in a minimum value in (a). The gray area shows the evaluated values of wac larger than the recommended maximum of wdc. (c) The obtained Tafel slopes for the selected W are obtained from (a), as a function of the cathodic window and wac. The black line represents the obtained results when the weight distribution is not applied. The black dashed lines show the Tafel slope of 0.24 V/dec obtained with the Tafel extrapolation technique for the “3,000 rpm aerated” curve. The curves for the wac resulting in minimal variability in (b) are highlighted in yellow.
