# No. 448 (Brown 1868): "Common lift pump. In the up-stroke of piston or bucket the lower valve opens and the valve in piston shuts;
# air is exhausted out of suction-pipe, and water rushes up to fill the vacuum. In down-stroke, lower valve is shut and valve in piston
# opens, and the water simply passes through the piston. The water above piston is lifted up, and runs over out of spout at each up-stroke."
# Model (cm, gravity on, Brown's view from in front, the pump cut away in half section). The handle is pinned to the top of the piston-
# rod and turns on a fulcrum carried by a swinging link from a lug on the cistern, so the rod rises and falls straight. The hand swings
# the handle (the only drive). The water is lumped vessels (src/fluid/vessels.c): the barrel under the piston and the water over it (up
# to the spout) are chambers swept by the piston (26.4208 cm^2); the suction pipe is the well at -2500 Pa (its water ~25 cm
# down). Both valves are real poppets on slides, held shut by their weight and lifted only by the difference of the pressures on their
# faces: the foot valve (4.5239 cm^2 hole) between the well and the barrel, the piston's valve (3.1416 cm^2) between the barrel and
# the water over the piston; each passes water (orifice, cd 0.62) as far as it is lifted. The spout lets out the water the up-stroke
# lifts. Generator: opencode-runs/vessels/gen448.py.
