is the direction that H20 goes down a sink change at the equator etc. ie clockwise/anticlockwise tks?

Yes and No.\n\nYes, the Coriolis effect is real, but is extreamly weak and does not influence us on an everyday basis.\n\nThe Earth's rotation does effect to a very minor degree the direction in which water will drain, the farther away from the equater you are, the more influencial the force it.  However, the Coriolis effect is negligible in everyday life compared to other influences such as any other disturbances in the water, wind, ....

Due to the effect, cyclones rotate counter-clockwise in the northern hemisphere, and clockwise in the southern hemisphere. However, contrary to popular opinion, it has no noticeable effect on the rotation of water in sinks and toilets - see the toilets/bathtubs section below.

it is one way (always +)\nwhereas other dims are 2 way (like + and -)\ni.e. distance=+50 km or -50 km\nbut time is always flowing in + direction

The hemispheric difference in the downdraft of fluids is a result of the spin of the earth, gravitational pull of the sun and moon, etc.  When we cruise along in our orbit, the spin of the earth itself, relative to the other gravitational bodies in our vicinity of this solar system, and the actual tilt of the earth on its axis determine the results of this actuality.

The water going down a tub rotates in relation to the earth's magnetic field. Water rotates in anticlockwise direction north of equator and clockwise direction south of equator.

I've been studying this stuff recently, and I'm pretty sure this is how it goes:\n\nK is now (-2,1) and D is now (-3,-2).\n\nFor future reference on determining rotations, simply turn the graph counter-clockwise one time for 90 degrees, upside down for 180 degrees, and for 270 degrees, just turn the graph clockwise once to see what the new cooridnates are.

The Coriolis effect can be observed in a small system such as a sink, but it is usually superseded by other factors such as "leftover spin" from filling the basin, basin geometry, convection currents etc.

The Coriolis Effect (though the flushing toilet is not a good example as engineering of the toilet could make the water rotate either way)

No, the Coriolis force can have an effect on other things, but not water rotating in a toilet

if you find out, you need to let me know...\nwhit_rocks@yahoo.com\n\nif you want to learn about more mysteries of life, i suggest you read Why do clocks run clockwise?

I would guess that it would slow down as some water is redistributed toward the equator.  This slowing would be imperceptable without the use of atomic clocks.  It would also be affected in another way.\nThe effect of the moon's gravity on the oceans is causing the rotation of the earth to slow.  Kind of a drag.  One day, the earth and moon will be in locked step, with the moon in the same place in the sky 24 hours a day.

You may be referring to the Coriolis Effect, which governs the rotation of very large fluids (like weather systems on earth), due to differential forces caused by the rotation of the Earth.  In a relatively small object like a pipe (or yes, even a toilet) the direction of rotation is either random or determined by the geometry of the object.

For the most part, yes. Low pressure systems in the Northern Hemisphere spin counterclockwise and Highs spin clockwise. The reverse is true in the Southern Hemisphere.

Hola Umar! Im just as confused as you are!\n\nNot Anymore, I got it! It is the Convection Zone!!!!!\n\nAbraham asked this question, I found it and did a double check and it is right!

Because of the coriolis effect. However, this is 100% not true. The water could either flow clockwise, counterclockwise or straight down depending on the shape and curvature of the sink/toilet

Actually its called the Coriolis effect and junglist is right\nDraining bathtubs/toilets\nA popular misconception is that the Coriolis effect determines the direction in which bathtubs or toilets drain, and whether water always drains in one direction in the Northern Hemisphere, and in the other direction in the Southern Hemisphere. The Coriolis effect is a few orders of magnitude smaller than other random influences on drain direction, such as the geometry of the sink, toilet, or tub; whether it is flat or tilted; and the direction in which water was initially added to it. If one takes great care to create a flat circular pool of water with a small, smooth drain; to wait for eddies caused by filling it to die down; and to remove the drain from below (or otherwise remove it without introducing new eddies into the water) – then it is possible to observe the influence of the Coriolis effect in the direction of the resulting vortex. There is a good deal of misunderstanding on this point, as most people (including many scientists) do not realize how small the Coriolis effect is on small systems.[1] This is less of a puzzle once one remembers that the earth revolves once per day but that a bathtub takes only minutes to drain. When the water is being drawn towards the plughole, the radius with which it is spinning around it decreases, so its rate of rotation increases from the low background level to a noticeable spin in order to conserve its angular momentum (the same effect as bringing one's arms in on a swivel chair making it spin faster).

Large scale flows depend on the Coriolis effect, which make the motion turn differently in each hemisphere. Therefore cyclones, hurricanes (though they are rare in southern hemisphere) and such events turn clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. As the spatial scale diminishes, the Coriolis effect loses importance. For tornadoes, for instance, it is still sufficient to make 98% of them to turn clockwise in the southern hemisphere and counterclockwise in the northern hemisphere. But, in 2% of the cases they turn differently.\nDust devils are small enough so that they can turn either way, independently of hemisphere.\nOf course, the water flowing down your sink is a very small-scale process. Coriolis effect makes no difference in that case.\nTherefore, it can go either way, both in Australia and in North America, depending only on the sink geometry.
