Suggested Edits for Flow Control and Measurement Design

More edits for the FCM section

In first section on flow control you mention the flow is too coarse, what exactly do you mean by that?
In drain system derivation, it is very challenging to read the final equations due to the purple color, either explain how to switch to light background or change color of equations
Link the Flow Control and Measurement slides where you reference the reader to them

For LFOM:

Having a picture or video of an actual LFOM in use could be useful for better understanding
The how it works section for the LFOM is still unclear to me. Maybe a more general explanation of weirs would be better, and then explain how changing the shape of the weir alters flow rate generally would be better? The challenge is expanding this section and keeping it clear while not making it too long
Also for the LFOM I think it would be valuable to explain that flow into the entrance tank is the same as flow out of the LFOM (which is sort of implied by saying that the LFOM does not control flow, but that still confused me)
I'm not sure if there are very detailed design documents for items like the LFOM and Almost Linear Flow Controller, but it would be cool to link them for those who want to learn more
Is there a general equation for flow through the LFOM as a function of water height? I get that they are proportional but if the equation is not too complicated that might help with understanding how it works

For Tank with Valve Derivation:

Explain that A_valve is the area of the pipe constricted by the valve, not the area of the pipe that connects to the valve. Also explain that this is hard to measure which is part of why you remove it
Update graphic in tank with valve derivation to show that height is a function of time, but h_0 is constant. Also when you should that Q is proportional to root(h), write out the full equation for h(t) (Q(t) ^2) to make it explicit. Consider adding this to both the derivation and design documents
When you include the minor loss coefficient, make it clear that this is includes the +1 from the head loss trick. Keep this constant in all sections where you include minor loss coefficients, and add an extra step in the fluids review where you add the 1+ to the sum of the minor loss coefficients
Also make it clear that h_tank is constant and not a function of time

For CDC Derivation:

Why are the sum of minor loss coefficients set to 2? Does this include the +1 for the headloss trick or not
Why can you just choose a maximum flow rate for chemicals and set the Q inside for that? Upon a second reading it seems like you are trying to minimize minor losses to achieve the maximum flow rate, is that correct? If so state that directly as justification.
Is the head loss constraint more limiting because of the available diameters, or for another reason? You say as you can see but that is not completely clear to me
Are there any circumstances you use for error equation for L_min, or is the design equation always based on head loss?
Are there any other design considerations for the CDC, or is it only the two equations listed? Maybe include them in a separate section at the end, and then mention them in the summary as well
Include a summary of the design process (something simple with the python functions necessary) that people can use as a reference when they don't need the entire derivation. Either put this in the derivation or at the end of the design document in its summary
Are the D_min equations ever used for design? You say they are not strictly necessary, but when would they come up? Could you use an example with a calculation?
A photo (or video of the operation) of a CDC in an AguaClara plant would be useful for understanding
Eventually it would be nice to have an example problem for the CDC that students could work through
