Archimedes principle and the relation between upthrust and weight of the fluid displaced

When a body is palaced in a fluid then Archimedes principle starts to express or address the behaviour of the fluid and the effect on the body by the fluid relating with density of the fluid, acceleration due to gravity, volume of the immersed part of the body etc.

The principle states that a force by the fluid in which the body has been placed can be found equal to the fluid displaced by the body. In other words, the upthrust on the body by the fluid is equal to the fluid displaced by the body. In some books the word 'upthrust' has not used and for this 'vertical upward thrust' has also been used.

Whatever they have used, finally we can understand the principle in th

e meaning that when a body is placed or put in the fluid, the body can immerse in the fluid partially or completely and the body feels an upthrust which is called the lost weight of the the body.

Archimedes Principle clearly says that the upthrust and the fluid displaced are equal. But some latest experiment show that the principle is not true where as it is accepted as the valid and irrefutable principle in physics. Some educational institutions also accepts the new claim of Bhabindra Kunwar (www.facebook.com/bhabindr.kunwar).

Therefore the latest result discovered by Kunwar shows that the relation in usual meaning between the upthrust felt by the body and the fluid displaced by the body is not right.
