Given 7kPa per 1 element I bet on those are not coated with plastic but made of instead as buckling is not an issue. The perforated plastic ~1/4" sheets squeezed with plastic spools by long studs and inserted in a piping straight run.
Assuming the turndown 1:2 the pressure drop per element is...
On homogenity of the mix downstream.
The cost of the most expensive static mixer is negligible compared to the risk of potential profit losses. A static mixer isn't a compressor, reactor, or furnace. It's a small, easy-to-manufacture piping element that someone could even make themselves from a...
Let me express in another words
No a straight run => swirl at the suction nozzle => flow maldistribution or assymetric at an impeller eye => cavitation and pump underperformance => impeller/seal/bearings damage => huge money losses => somebody shall take the responsibility
Ask the piping...
How is the swirl oriented relative to the impeller(s)? Was this pump tested for uneven flow?
Was the impact on NPSHR and bearing&seal service life measured or accouted for? Is there a NPSH margin to compensate for an NPSHR encrease? Is there a design margin to compensate for a penalty in pump...
Is there a need in theorizing of the fluid properties? How are you going to prove those are relevant?
Why can't you provide a simple measurement of a controlled volume?
Or this is a thesis paper?
Just stumble upon the ASME's report. Maybe it can help
ASME STP-PT-049 Investigation of Temperature Derating Factors for High-Strength Line Pipe. ISBN: 978-0-7918-3426-8
You want to know the allowable accumulation in the boiler as per Sweden jurisdiction codes, correct? 3% or 6% or 10% or 15% or whatever, correct?
First ISO 4126 is irrelevant ot PV, it is referred to PSD. Second in Sweden jurisdiction the EC's PED is applied.
As per my experience you are...

See below and bolded in CCPS above . Note that ExxonMobil and CCPS do not distinguish hydrogen and hydrogen-hydrocarbons as API does.

some pointers can be found at the EIGA's guide

The snuffing steam design can be found in ExxonMobil in the next post. Note the pictures in the next post - ExxonMobil guides the exhaust upward with no a rain cap.

(1) a very expensive, (2) complicated, (3) occupied a lot of space, (4) requiring a personnel attention, and (5) not a robust mean creating (6) a dangerous O2 depleting zone around a the vent exhaust and PSV drain both - it should be added.
I am not familiar with a multiport valves concept in the upstream industry.
Given the Emerson's doc shared by LittleInch the stagnant flow is not an issue.
I would address to the reliability of the multiseat on the figure 3. This detail:
(1) looks less robust than a seat of a conventional gate...
For dangerous clean gases (N2, H2, CH4, steam) we practice to connect a weep hole to a small-bore drain and route that downward to a safe location that takes into account the exposed dispersion areas. There are reasons to increase metallurgy of the drain to prevent rust blockage.
As an option we...
