About how much would you surmise the weight of an electric horizontal

The high pressure water in=rush compresses the air in the system.
The velocity slows as the air pressure is compressed. I don't believe there
is water hammer potential because the air creates a cushion.

What state are you in?
Can I assume you are planning quick response sprinklers.
Then why not 900 SF area of application allowance?
What part of the code is AHJ using for this requirement.
There are residential rules in 13.
Use residential heads with .10 density

Water company requires BFP not NFPA 13, 24.

Sometimes you have to wake me up. I just saw this question.
Went to google. Tyco uses EC #'s. I saw EC 5, 8, 11, 14 but no EC 10 in
there listing.
Call Tyco they can help. What size is pipe thread. 1/2 or 3/4"?

What is the sprinkler spacing?
Staggered spacing was quite common before 1940.
Newer heads installed?
High pressure water supply connected?
It likely will barely do .10 density or maybe .15 with moderate pressure.
FM used to allow 3-5 psi at end head for pipe schedule.

Sprinklers don't spray upward. If Foam plastic insul is combustible it burns
faster
than the sprinklers can operate and water is not sprayed upward.

Some threadable light wall pipe was galvanized on the outer pipe wall but
not inside the pipe.

I think the allowable storage in light hazard occupancy is 6-7Ft.
Think about a light hazard library with rows of book shelves.

How did you get a pitot higher than the residual? Can't happen. Gage error?

Without a pitot at the outlet no way to tell.
You can try to hydraulic calculate the flow through the 2 valve, ells and
pipe length using static/residual psi at the riser.
