Large Increase in Jacket Flowrate

Consider a step change of 1.0 (from 1.5 to 2.5 in jacket flowrate. The responses of the linear and nonlinear models are shown in Figure 3. The linear response is qualitatively the same as the nonlinear response, but the magnitude of change is different. The gain (change in output/change in input) of the linear model is greater than the gain of the nonlinear model.
