What is the direction of water swirl when plug from wash basin is pulled out?

Answer:

It depends primarily on the geometry of the sink. Under ideal conditions it probably would be anti-clockwise in the northern hemisphere and clockwise in the southern hemisphere due to the Coriolis effect, but the geometry of the sink is a significantly more powerful factor than the Coriolis effect.

The flow of water down drains has nothing to do with which hemisphere you are in (like we're all led to believe); the Coriolis effect is much too small. It will be determined by random motions in the water (or, in the case of toilets, by the direction of the incoming water). Experiments have been done which show that the water will indeed drain in opposite directions in the northern and southern hemispheres if you are careful enough to eliminate all motion in the water first; this is very difficult to do, and will not happen by itself (it also requires perfectly symmetric containers).

I stay in Michigan (the only shaped like a mitten) interior the USA interior the Northern Hemisphere. The water swirls clockwise basically like it does in all the NH. it fairly is the rigidity of the Coriolis. I laughed at &anti clockwise&. we are saying counter clockwise.

always anti clock wise imagine a bathtub on a plane you pull the plug and go to australia ,does everybody think that when you cross the equator it changes direction rediculous , because of the direction we turn around the sun every thing follows, vines all over the world wind them selves anti clockwise around the trees winds,ocean currents ,weather patterns ,the way the spirals in our bones devellop,the spiralling devellopment of branches on trees,the direction of the spiraling action of tornados ,spirals in rivers ,etc i have seen vines all over the world ,and all go in the same direction ,if you change it they contort and reverse to the original position.
