Why the rotation direction of water in a sinks changed after crossing the equator?

The twisting effect of the Coriolis force is real and does influence certain large things like the movement of air masses, but the effect is so small that it plays no role in determining the direction in which water rotates as it exits from a draining sink or toilet. The Coriolis effect produces a measurable effect over huge distances and long periods of time, such as storm systems, but don't apply to your bathroom or kitchen. Toilets and sinks drain in the directions they do because of the way water is directed into them or pulled from them. The configuration of taps, drains and the surface of the bowl is responsible for the direction of the water draining through, overwhelming the coriolis effect.
It's a bit of a urban myth. People on the equator sometimes demonstrate it to tourists, but these are rigged.

What direction does the wind move if there is a high pressure system?
The coriolis effect causes wind to move in a clockwise direction in the northern hemisphere if there is a high pressure system, and counterclockwise around high pressure in the southern hemisphere. The coriolis effect is caused by the spinning of the earth. Points near the equator actually move faster than those near the poles, because they have farther to go for a complete rotation.
What is the period of rotation of the sun about its own axis?
Around the equator the Sun rotates once every 24.47 days. However this number changes with latitude, because the Sun experiences what astronomers call differential rotation. This is because the Sun is not solid like the Earth but gaseous. At the poles the rotation period is longer, about 33.5 days.
What is transport wander in free gyroscope?
Transport wander of a gyroscope is apparent when the gyroscope crosses a meridian that is converging with another. So, at any latitude other than the Equator, any East-West movement will cause transport wander. As North-South movement involves tracking along a meridian (and not crossing) then no transport wander occurs. Although East-West movement along the Equator does involve crossing meridians, because all meridians are parallel at the Equator no transport wander occurs.
What is The velocity of the gravity of the earth?
At the Equator it spins at 1,000 mph. At 60 degrees N/S, the circumference is half the distance than at the Equator so it inly spins at half the speed ; 500 mph. At the poles N/S it spins on the spot. 0 mph.
Which direction does the California current flow?
It flows from the north, where it's cold, to the south.
The crossing the line ceremony marks a ship's crossing the?
The ceremony is used to celebrate a person's first sea crossing of the Equator.
The coriolis effect refers to a change in direction caused by?
The Coriolis effect is caused by the Earth's roration.
What is used to determine the direction of the wind?
Wind direction is determined by friction ,or the lack thereof ,surrounding the earth surface. Warm air from the equator rises, moves towards the poles, falls and returns to the equator. crossing water decreases friction, crossing a mountain increases friction.
Is the speed of rotation at the equator greater than that in Canada?
yes. rotation at equator is roughly 1000 mph, rotation at any other latitude is about cos (latitude) * 1000 mph.
Where does the crossing the line ceremony mark a ship's crossing?
When a ship crosses the Equator.
How long is the suns rotation?
25 days for a rotation at the equator, 34 days for a rotation near the poles.
Where does earth's greatest speed of rotation occur?
At the equator
What is the difference between rotation rotation axis equator?
rotation is the spiinning of the planet on its axis and revoulution is the orbiting of the planet around the sun
What is the difference between rotation rotation axis and the equator?
rotation is the spiinning of the planet on its axis and revoulution is the orbiting of the planet around the sun
Which planet has the biggest bulge at the equator?
The relatively pronounced bulge is due to, Jupiter's rapid rotation rate of 9 hrs 56 mins, and Saturns 10hrs 32. As the planets are made of gas this high speed rotation pushes out the gas at the equator.
What is the slow rotation of the plane of the celestial equator called?
Precession.
The Arctic Circle is in what direction from the Equator?
the Arctic Circle is north of the equator.
