     "These diagnostics can help give us an idea of what may be causing problems in our model. From the output above, we can see that the variables with large Jacobian norms (i.e., high sensitivities) are the outlet flow rate and temperature, as well as the rate-based extent of reaction. We can also see that the constraints with large Jacobian norms are the enthalpy balance and H20 material balance for the reactor. Understanding what this means however is often complicated and requires some thought.\n",

-    "For example, one might wonder why the volumetric flow rate at the outlet of the reactor is so important as it is effectively determined by the inlet flow rate (due to the water balance effectively conserving volume). However, it is important to realize that from the point of view of the solver, the outlet flowrate is a free variable that can be manipulated, and that changing the volumetric flowrate at the outlet has a significant effect on the outlet concentrations (all other thing kept constant). Thus as far as the solver is concerned, the outlet volumetric flowrate has a significant impact on the solution. This also explains why the H2O material balance is so important, as this is what governs the outlet flowrate. However, the material balances and concentrations of the other species in the system are what really matter, but this is not reflected in the model Jacobian. Once of the goals of scaling the model should be to balance these to ensure that the water balance does not come to dominate the other species.\n",

We should always also keep in the back of our minds whether additional work is worth the effort, and if we risk over-tuning the scaling for the specific property package we have.\n",

Firstly, we the unit-level constraint that says that `rate_reaction == 0` for all rate-based reactions. When considering scaling of a constraint we should ignore any 0 terms, thus this constraint has only 1 term and so we should scale based on this. If we use the ``scale_constraint_by_nominal_value`` method for this it will ignore the zero for us, the scheme used does not actually matter as there is only one term to consider.\n",
