From CEE4540_Master created by IanCullings : AguaClara/CEE4540_Master#18

Here are a bunch of areas I thought could be edited on my initial read through:

• [ ] When listing the assumptions for the Bernoulli equation, you state that "friction by viscous forces must be negligible" but never define exactly what that means. Consider adding a sentence or two to define that and explain generally when that is true or not
• [ ] Under the energy equation where you include terms for energy gain/loss from pumps and turbines, does that mean only pumps and turbines, or any system that adds or removes energy from the fluid mechanically? Consider elaborating on that slightly
• [ ] Consider adding a diagram showing friction and shear in the major losses section
• [ ] Define laminar and turbulent flow regimes before major losses section
• [ ] You use the continuity equation many times throughout, but never really define or explain why it is valid
• [ ] In the orifice section, you state that the equation is for a horizontal orifice, but the picture you use to explain it shows a vertical orifice.

Feel free to ask me for clarifications!

From CEE4540_Master:

isakaminsky:

• [ ] Introduce variable for head earlier maybe?
• [ ] Introduce control volumes and streamlines

ananya-gangadhar:

• [ ] For Laminar and Turbulent Flow, specify the approximate value/range of the Reynold's number for each type of flow in the second paragraph
• [ ] Streamlines and Control Volumes, second paragraph: "Imagine" instead of "image"?
• [ ] First image in Streamlines and Control Volumes doesn't load
• [ ] The link to derivation of minor losses equation doesn't work

IanCullings again:

• [ ] Is this textbook aimed just for Cornell students or for anyone interested in AguaClara plant design? If you're aiming for the latter, I would remove references to CEE 3310 and replace with "your fluid mechanics course" or something similar
• [ ] I'm getting an error with the latex equation in the head loss trick section, above the words "We now get"

zoemaisel:

• [ ] Consider replacing "heavily used in the course" with something more general like "used in this textbook" or "in AguaClara design processes"
• [ ] Punctuation errors in paragraph beginning "If you wish to review fluid mechanics"
• [ ] Replace "document" with "textbook" under Introductory Concepts introduction paragraph
• [ ] Update references to aide_design to the new, appropriate term
• [ ] Bold "streamlines" when the term is introduced
• [ ] Head loss vs. headloss
• [ ] Include a place where major vs minor head losses are clearly shown (a simple table?)
• [ ] Some of the figures do not follow the convention named at the beginning (i.e. using purple line to show streamlines)
  • [ ] Using purple on top of blue is hard to see. Consider changing purple lines to something more clear?
• [ ] I think that using parentheses to highlight letters for the variables is confusing (ex: (e)xpansions)

[juanchon998]

• [ ] Mention that the "head loss trick" can or should be referred to as 'exit losses'

Create new section for weirs!

Weirs are critically important to understanding how water flows through an AguaClara plant. I propose that they be discussed in this document.

@clare45 does anyone currently working on the textbook want to take this up? While I'm here, is there any subteam lead for the textbook team (you?)? Who should I talk to regarding general textbook things?

[clare45]

I guess I can act as STL for textbook. I'll reach out and see if anyone want to add it. That would go in the fluids section? I can now add a todo on that Issue

Thank you!
