# No. 475 (Brown 1868): "Bilge ejector (Brear's patent) for discharging bilge-water from vessels, or for raising and forcing water under various
# circumstances. D is a chamber having attached a suction-pipe, B, and discharge-pipe, C, and having a steam-pipe entering at one side, with a nozzle
# directed toward the discharge-pipe. A jet of steam entering through A expels the air from D and C, produces a vacuum in B, and causes water to rise
# through B, and pass through D and C, in a regular and constant stream. Compressed air may be used as a substitute for steam."
# Model (cm, gravity on, seen from in front, cut away in half section). Compressed air (Brown's substitute for steam: the model has no
# condensation) at 3 bar gauge comes in along A through a cock a hand opens and shuts (swung open over 7.5 s, +0.8 rad at 1/30 Hz, the only
# drive) and leaves A's nozzle (0.3 cm^2) up into C. The water is lumped vessels (src/fluid/vessels.c): B (from its foot in the bilge
# up to D), D and C are chambers of water under air; the bilge is a well kept at its level. The jet pump (openspec add-jet-pump): the
# nozzle's stream gives up its momentum to what passes from D into C, a pressure rise mn (vn - vm) / A_C across that throat; it carries D's
# air out first (the vacuum that draws the water up B), then the water, which rises up C and runs out of the spout (the cock is opened once and held).
