6.7 Would any difficulties occur if the process were not at steady state when a process reaction curve experiment was initiated? |
Process Reaction Curve |
6.8 What is the signal-to-noise ratio for the output data in the graph? Would this data be acceptable for estimating parameters using the process reaction curve method. |
Process Reaction Curve |
6.9 As a rough estimate, what accuracy do you expect from the empirical modelling method? Express your answer in percent error in parameters. |
6.10 The experimental following data have been obtained for the fired heater process shown in the figure. Evaluate the data to determine whether the data can be used for the process reaction curve calculations. |
Experimental Method |
6.11 Two process reaction curve experiments were performed, both from the same initial operating conditions for the continuous flow stirred tank in Figure 6.2. Suppose that the temperature responses were very different. Discuss reasons why this situation might occur and methods for determining the cause of the discrepancy. |
