Don't place undue confidence in what the pump manufacture's rep, or the results produced by software or web pages available from the manufacturer. The rep may have never before corrected a performance for a glycol application. The software or web pages may have been written by recent computer...
A preliminary look at results from the selection tool linked above suggests it may produce exactly the same head-gpm curve regardless of the fluid viscosity. It does correct the BHP curve based on fluid density. The efficiency and NPSH curves also seem to be unaffected by fluid viscosity...

The corrections become larger as the fluid temperature decreases.

I would still use the current CSI system as a basis. It has more granularity than their previous 16-division system, and most of their Section numbers could be stable enough for the most complex details.
Whatever section numbers CSI tweaks, you are free to ignore their "new and improved"...
Not what I have done, but first imaginings of what I would do:
1. Rely primarily on section level numbers.
It seems that using paragraph numbers:
Would be a maintenance nightmare when the specs are updated.
Could be confusing five years from now to find reference to detail D-15150-2.A, which is...
I haven't received notifications for most replies.
Europipe is correct, I meant incompatible chemicals on the outside of the pipe; which should have been clear from the context.
I thought the claim about grease from french fries ruining a pipe was ridiculous until I did some research.
Crude...
How long does this installation need to last?
Though this is about sprinkler piping, the same reservations might be appropriate in other applications:

I haven't looked for code references, but codes prescribe a minimum standard. If there are economic reasons to exceed code requirements, then it is the call of whoever is paying for it whether they want to exceed the code-required minimum standard.
Depending on the sizes of the pipes and the...
I also understand "hot tap" to mean making a connection to a pressurized line while the pressurized line remains in service. I have seen it used in reference to pipes conveying fluids that are not potable.
What the OP seems to be describing is a "mechanical tee."...
I asked before: "Why do you think it is a problem that the louvers 'reduce the ventilation?'"
Is the bread getting moldy because moisture can't get away?
Is it losing water weight because higher temperature in the shed is driving moisture out and selling the bread by the pound results in less...
Suggestion: Enjoy your weekend; don't worry about this.
Why do you think it is a problem that the louvers "reduce the ventilation?"
If your modified louvers let in any rain, then you will probably hear about it:
We didn't have this problem until Rookie37 cut up the louvers. Actually, he isn't...
There was apparently money to install louvers and mesh. Is there money to install a fan?
Or a roof turbine ventilator?

Seriously? A pptx file?!
This could have been done with a screen capture saved to png format.
Markups can be done in any number of image editing programs.
Then viewing your image would have been one click away within the browser.

Transpiration of plants is directly proportional to biomass production

Interesting question.
Some searching led here:

Still not enough information from the OP.
Why are the heat exchangers installed? If they are only to separate a 15 psi steam boiler from water systems operating at higher pressures, maybe no controls are needed at the heat exchanger.
I think the OP's question is too general. There are too many personal preferences on how things "should" be connected for there to be a one-size-fits-all schematic. I imagine the members of this forum could come up with at least 50 schematics that would be different in some way.
The OP provided...
Not a standard term, AFAIK, but it is descriptive: "trainwreck tee."
