if you were standing on the line of the equator how would the water run down the drain?

Answer 1

This would depend upon the movement of the water in the basin or toilet before the drain plug was opened.

If the water was perfectly still, theoretically, it would run straight down the drain. If the water had the least little motion (such as from hands scrubbing) then the direction of the water movement would generally cause wither a clockwise or anti-clockwise rotation or the water as it emptied the basin.

Often toilets force the flushing water into a direction, so this would be active in a toilet flush.

Answer 2

Water going down the drain, toilets swirling, etc. do not depend on the rotation of the Earth. This is an urban legend. The Coriolis force is present, but it is, in general, much smaller than other effects such as the exact shape of the toilet or small currents from the fill pipe.

Even objects as large as tornadoes occasionally go around "backwards", against the Coriolis force.

That being said, the Coriolis force is zero at the equator, and its effect is zero. The water going down the drain will still tend to swirl, but that's because of the shape of the bowl or the small currents from the fill pipe. Just like everywhere else on the Earth, it could swirl either way.

Note, however, that hurricanes never form exactly on the equator, and that's because the Coriolis force is zero.

Answer 3

If the earth were to rotate perfectly around the equator and didn't rotate round the sun and there were no currents in the water - then it would run straight down the plughole without swirling.

In practice none of the above is ever true and local conditions (the currents in the water) would ensure that it runs down the plughole in the direction of the strongest current (usually clockwise).

Answer 4

The water would definitely run straight through the drain.

Answer 5

The movement of earth has nothing to do with motion of earth water always flow from a high ressure zone to a low pressure zone In the equator also it will be flowing in the same manner however winds definitely show signs of coriolis force caused by the movement of earth.

Answer 6

Cast the drain to the south

Answer 7

in the direction of the lower pressure. If you are at a place where the pressure is exactly the same, i suppose it might not create a vortes, rather fall straicht down & air bubbles would force their way throught the top.

Answer 8

Toward the center of the earth. You know, in the direction of gravity. (No predictable coriolis).

Answer 9

It would pour straight down without swirling.

Answer 10

same as it would in any other place
