I dunno. Reverse peristalsis can be pretty quick and result in a pretty steady flow. I’d imagine they’d have to adapt to develop that regardless of how they’re going to expel things, similar how giraffes are able to chew their cud despite their long damn necks. Wouldn’t be projectile vomiting as we describe it though. In the end their entire neck is a pump.
Good point. However, the height difference between giraffes and Brachiosaurus is still quite significant. I am not well versed enough in the exact mechanics of this but maybe it won’t scale well. Additionally, the neck of Brachiosaurus was probably far more flexible than that of a giraffe due to the higher number of vertebrae so they may be able to lower their necks more easily which reduces the pressure to evolve powerful pumping mechanisms.
That’s assuming it doesn’t lower its head to the ground like a cat
Which it would probably do because I don’t think it can pump stuff 10 meters high with its stomach

Or get on an old family rug first like a cat
As I recall there was a study of its neck bones that suggested the lowest it could tilt its neck was 6m above the ground or something.
Sounds inconvenient for drinking
My cat only throws up on my bed, preferably right beside my pillow, no floor involved.
