Topics in this category will not be answered by Professor_Kirby_Bot. You can ask questions of the community and of Professor Kirby, but there is no guarantee that questions posted here will be answered quickly (Professor Kirby Bot, on the other hand, is prompt in responding)

This category is about the engineering of fluid mechanical devices, which Prof. Kirby calls fluid machines – how they work in practice. It is meant to be focused on the fluic mechanics but is designed to prioritize their practical operation more than just as an example for a fluid mechanics question/concept.

Appropriate for users wanting partial or complete solutions to classwork-style fluid mechanics problems. Solutions to simple, textbook-style problems are typically manageable, as is guidance or partial help. Large-scale problems, problems requiring detailed analysis or simulations, are typically out of scope.

The General category is used primarily for administrative topics– neither Professor Kirby nor Professor Kirby Bot typically respond to topics in this category

The world, especially the internet, abounds with incorrect or misleading descriptions of how fluid mechanical systems work, many of which are repeated over and over again. These topics are often “controversial” to the lay audience, although there rarely is any disagreement between fluid mechanicians about these things. This category is for resolving questions where multiple sources disagree or where the purported explanations come from an unreliable source.
