One setup has the improved feed accelerator equipped with overspeeding vanes
and smoothener that facilitated feed entering the rotating
pool with matched tangential speed of the pool. The other setup
has a conventional feed accelerator that has two open ports in
the hub at a smaller radius resulting in poor feed acceleration from
the radial drop of the feed onto the pool surface at a larger radius.
As such, the feed velocity is much below that of the rotating liquid
pool.
