#648651 — Hourglass Question

An old question from the 1970s that I never 
figured out.

What governs the speed of flow of an hourglass?

I mean what principle.  What's going on.

It's not viscosity (no transport of x momentum in 
the y direction etc.)

It seems like it's the time it takes something to 
call out of a lockup condition and clear the mess, 
leaving it up to the next lockup condition, but 
what the hell equation is that?
-- 
rhhardin@mindspring.com

On the internet, nobody knows you're a jerk.

Time as measured by an hourglass should appear to go by faster in a strong gravitational field, and come to a stop in space.

Test it AA. Next time you are on a starship, take an egg timer and sit 
it on one of the gravity plates. Turn the plate up to "high" and measure 
the time with a tricorder. Next turn the plate "off" and again measure 
the time. Report back to us what you found.

China of old used water clocks.They gave away glazing secret to get UK mechanical clocks.Sun shadow was used but very falty.Electric clocks run the same way a electric train's motor.Still do.Age of Earth done by radioactive decay of lead I think.Done by a man named Anderson I think,and he got Nobel.H.Ford hated him for he tried to stop putting lead in gas.He did get the clean air act in in 1976,but 20 years to late. Lead was the down fall of Rome,and now USA. Lead in the brain upsets the thinking. Lead in the end will create what humankind is doing today. Treb has no lead in his system Trebert

Clearly Bert has been sucking lead his whole life and now everyone can 
see the result. Reber you are a senile moron commie. Electric clocks DO 
NOT use the same motors as electric trains (toy or full sized) 
Swinebert, you like Banjo have NO idea how anything works and are just a 
big-mouth pig-thief like he is.

Tell us what kind of motors you think electric clocks have. We'll wait 
right here for you to get coherent.

Hourglass, electric clocks, pig-thiefs, commie motors, radiation 
protective lead shorts, gravitational coherency, shadows and gasoline,
stopping in space...

what is this thread about ? now, not the future now Trebert.

sadly lead is still in a lot of water systems

https://www.cdc.gov/nceh/lead/tips/water.htm

watch out for white powerish stuff on lead weights, like for fishing, 
that form of lead oxide is water soluble and can poison quickly.

Anyhow, the Hurricane will miss me entirelly!!

Yeah, I noticed that white powder on some old fishing weights I used to have.  Also they had a strange acrid smell.  I didn't think they were safe.

Well good for you.  The raging forest fire near me has settled down a bit, but it could still be a threat.  We all have our problems!

Water is Mexicale's biggest.Hard to burn a 50 foot palm. What they call here a forest is in reality tall weeds. Nice day in the mid 80s.Sun so bright it hurts my pretty blue eyes. One year olds wear sun glasses.I have 4 pairs.Buck each at the dollar store,and are very nice.I look 5 years younger wearing them.TreBert

Lead is better than radioactive elements.  Once a big nuclear war has strewn them everywhere, will miss the docile lead, but will have to wait millions of years for them to decay back into lead.

Earth having lead everywhere is no longer a safe planet for higher animals.We do not realize the harm it is doing.Lead killed Rome.Now its much worse than then.Trump,or Kim will make a bad choice and humankind will be dead before they hit the ground.  Treb has written this post  Treb

Try this start: the sand above the hole consists of locked up unstable structures, each 
stabilized by the structure below it.

The one at the bottom goes unstable and falls, freeing the one above to begin going 
unstable.

So there a distance between structures, an instability growth time to collapse.

Fluid approximations do not work well at the scale of sand in 
hourglasses for most hourglasses. Almost all of the sand is statically 
braced against the walls and floor of the hourglass. Instead, you have a 
small region of instability above the hole where it is not possible for 
the sand to be braced; as that unstable portion falls through the hole, 
more falls in from above. There is slow flow of sand downwards, but it's 
still mostly statically braced. Thus, to a first approximation, flow 
rates are determined by grain size and shape (and material), and the 
immediate geometry around the hole (predominantly the size).

Here are the other factors that affect the accuracy of an hourglass:

     The amount or volume of sand used
     The size and angle of the glass bulbs
     The quality of the sand or granular material. It must be fine, dry 
and consistently formed so it can flow smoothly. (Some substances used 
in the past were fine grain sand, powdered eggshells, and powdered marble.)
     The width of the neck
     A tight seal so no moisture can get into the chambers. Moisture can 
add weight to the sand or clog up the neck.
     A flat and level surface on which to rest the hourglass

Thanks!  Did they get the sand bridges and instability the same way I did, by thinking about 
it, or is there a dynamic simulation somewhere?  It was wondering how to program a simulation 
long ago that first started the open question for me.  It wasn't and isn't obvious what to 
program, unlike say fluid particles or stars in a galaxy, or plasmas, where the particles can 
move independently of each other with the exception of neighboring particles or a global field.

Sand motion depends on a configuration over potentially long distances since the particles 
touch.

Incidentally, even with a fluid, the weight is supported by the sides of the container, with 
the exception of the column over the hole.  It's the indifference to pressure at the hole that 
distinguishes the two.  The sand bridges, if unbroken, don't let the pressure through.

Nope.
