What keeps the Liquid from
coming out?
Or!
What causes the
squeeze? [By Franklyn Dono]
A Chronicle about it
Creating
a vacuum is naturally not possible,
well since it’s preceded by an extreme low pressure that certainly will cause a
surge of something to fill it up. A number of chaotic and catastrophic events
like the tornados; tsunamis; earthquakes and tremors; flood; volcanic eruptions
and the hurricanes occurs naturally as nature’s own way of stabilizing itself
as it quests for equilibrium reducing even the slightest plausibility of a vacuum. The “one Hole Concept” tells
why trying to pour liquids off a Jerrycan; a Can or a Tin [like a tin of liquid
milk] with just one outlet, these are bound to occur:
a.
A
squeeze [rife with plastic cans];
b.
A
breaking flow of the fluid out from the container;
c.
A surge
of air gushing into the container with every break in the flowing liquid out
from the container; and/or
d. No squeeze
for a metal or a steel container. The liquid stays stagnant within and doesn’t
come out [observe a steel tin of milk with one hole].
“Squeeze” and “no Squeeze”
Aside
the ‘void’ property of a vacuum, a vacuum is also characterized by an extreme
low pressure {reiterated}. Consequent to this extreme low pressure property of
a vacuum, it becomes difficult for a vacuum to be created [human enhanced] but naturally
not possible if nature’s course is kept un-altered withal. Observe a vacuum
cleaner [human enhanced vacuum], notice that the aptness and efficiency of the
vacuum cleaner is due to the vast difference of its pressure [an extremely low
pressure] from the ambient pressure [i.e. standard atmospheric pressure], which
causes a surge of dirt and air particles into the vacuum cleaner as a means of
making the pressure in the vacuum cleaners vessel equal to the prevailing and
surrounding atmospheric pressure and to fill up the vacuum. These, emphasizes with
jaunty and pithy the essence and likely results of the one Hole concept.
The act
of pouring the content of a vessel/container e.g. a plastic Can, via its opening
[just one hole] without allowing air to go in the plastic container means
causing a void in the container eventually. For a plastic vessel/container filled
to the crux, emptying it of its content with a single opening makes it squeeze
[a means of preventing a void/vacuum] because a corresponding extreme low
pressure is built by the act. Since the ambient or surrounding atmospheric pressure
[standard atmospheric pressure, “SAP” equals 760mmHg/1atm] stays still and
doesn’t drop, it becomes more than the pressure within plastic Can consequent
to the act of emptying the Container off its content. Following this aura, the
effect of the prevailing atmospheric pressure is felt by the exterior walls of
the plastic Container, causing it to shrink in size as it squeezes, thereby
reducing the volume or space of the Container that could have being completely
empty or void [i.e. the squeezing of the plastic can prevents a vacuum or a
void from occurring, quite naturally].
Somewhat
natural and unavoidable, is the breaking flow of the liquid content out from
the container. With each break, a surge of air rushes in-to the container to
replace the volume of the liquid content poured out and fills the space which
it occupied. However, for the content of the plastic Container to come out at
all and for it to squeeze, tells of a relatively low “Compressive Strength” [the
capacity of a material or an object to withstand a load per unit area tending
to reduce its size or volume]. The
small and low “Compressive Strength” of plastics is apparently not strong
enough to resist the shrinking effect of the ambient atmospheric pressure of
760mmHg/1atm, ergo following the squeeze of the plastic vessel/container, its
contents gushes out through a single hole with the vacuum tendency avoided by
the shrunk volume or size of the plastic vessel, Jerrycan, Can, or bottle. All
these affects the rate and degree of the shrink or squeeze of the vessel,
container, can or Jerrycan.
Hints: for containers or vessels Whose
Compressive Strength is strong enough to resist the shrinking effect of the
760mmHg atmospheric pressure [SAP], trying to empty it off its content with a
single hole, the liquid content of the Container; Vessel; or Can e.g. a tin of
milk, stays still within the container and will not come because if it comes
out, a vacuum or a void ‘an empty space’ will be created. Remember! It is
naturally not possible for a vacuum to be created.

Metals are known for their high Compressive strength, likewise steel and glass. This unique property of metals/steel renders the squeezing and shrinking effect of the atmospheric pressure [760mmHg/1atm at SAP] on the exterior walls of a steel container to naught, even when a vacuum has been enhanced in the container. Consider a tin of milk for example. With one hole, the liquid content within the tin will not come out [cannot be poured out] naturally except when enhanced by suction thereby leaving the tin empty as a vacuum. Because the compressive strength of the tin/steel container is very high, the liquid content of a tin/steel container remains inside of it since the ambient atmospheric pressure is not heavy enough to squeeze the Steel container and reduce its size to the volume of its content left in the course of pouring out its content through a single hole on the steel container. However, if the pressure/load on the exterior walls of the steel container is enhanced by any means possible or raised to a point where the liquid content inside the steel container starts coming out i.e. the pressure now exceeds the compressive strength of the steel container, the steel container squeezes simultaneously preventing any vacuum tendency. The squeeze observed reduces the volume of the steel container in the exact same manner at which the liquid content of the container comes out consequent to the enhanced or raised pressure.

Noteworthy:
for a steel container; plastic container or any container, its liquid content
can be poured out easily via a single hole when the container is perforated at
two spots [having two holes] because as the liquid content inside the
containers comes out through one hole, the exact same volume of it is replace
by air simultaneously which gushes into the container through the other hole.
Ergo, for such a condition withal, no squeeze or breaking flow of the liquid
out from the container is observed neither will the content of the container
stay still inside of it.
