By increasing pipe sizes with velocity you are in effect increasing the
density since the required pressure is likely far below the available water
pressure. The industry rules for hydraulic calculations are pretty
conservative if the correct density has been established for the occupancy.
If I understand this correctly, are you creating a loop feed for the
hydraulics? You need check valves and control valves at both ends.
I don't think you need a standard AF loop beyond the RPZBFP. You do need to
control pressure but in a different way.

One more comment: You still need the flowing pressure OR a pitot psi or at
least a residual psi at the test header. If the BFP is becomes restricted
the pressures are necessary to determine the next step. Without psi and flow
the K has no meaning except to have a basis for the device when in new
Google Pillow Tanks

Can there be a design issue in question with hydraulic calculation method or
head types that does not provide life safety.
Standard response sprinklers versus the required quick response heads would
be an issue.

meant for storage. I have done many sprinkler assessments over the years and
designed the necessary hydraulic upgrade to the system. This is a building
code issue. There needs to be a mandatory assessment when the tenant change
occurs and at 3-5 years intervals thereafter per NFPA 25.

I could see a lot of stress on the valve when it is nearly closed
restricting the flow but not when it is fully open.

The pipe going through the wall must be restrained and anchored to the wall
or floor penetration. Link seal is a water seal.
