# No. 466 (Brown 1868): "Hydrostatic press. Water forced by the pump through the small pipe into the ram cylinder and under the solid ram,
# presses up the ram. The amount of force obtained is in proportion to the relative areas or squares of diameters of the pump-plunger
# and ram. Suppose, for instance, the pump-plunger to be one inch diameter and the ram thirty inches, the upward pressure received by the
# ram would be 900 times the downward pressure of the plunger."
# Model (cm, gravity on, cut away in half section, seen from in front). A hand lever on a standard works the pump's plunger (the lever
# swung +-0.3 rad, the only drive). The pump draws from a cistern through a flap in its head and forces the water through a second
# flap along the passage under the press's bed into the ram cylinder (here 6 cm bore against the plunger's 2, 9 times
# the area). The solid ram carries the platen and the bale on it up against the follower, which hangs under the crosshead on its
# springs (the goods' resistance: 1500 N/m, preloaded 2 cm). The water is lumped vessels (src/fluid/vessels.c): the cylinder
# under the ram with the passage, and the pump's head and barrel under the plunger, are closed chambers of water (bulk modulus 2e+07 Pa)
# that the ram and plunger sweep; the pressure under the ram is the one that drives it, the same that the plunger must overcome, so
# the force on the ram is that on the plunger times their areas' ratio. Each flap is moved only by its weight and the pressures on
# its faces, passing water as it opens (fully at 0.5 rad). There is no let-back valve, so the ram stays where the pump leaves it.
