Briefly describe the key fluid physics/flow regimes which exert an influence on the DOAPs. Ideally this should draw together into a coherent picture the associated UFR descriptions together with any important interactions which are AC specific. Mention the UFRs associated with this AC that you have considered in drafting your best practice advice. ''Access the Knowledge Base to find the UFRs associated with your AC''. | Briefly describe the key fluid physics/flow regimes which exert an influence on the DOAPs.

Briefly discuss the sensitivity of the DOAP predictions to these uncertainties and their impact on the BPA. In particular, can clear, unequivocal BPA be given or is it necessary to introduce appropriate caveats. | Briefly discuss the sensitivity of the DOAP predictions to these uncertainties and their impact on the BPA.
