is it something related to the drinking water or bore water.

In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place, so that it can be weighed.

In physics or chemistry, water displacement is used directly to measure an object's volume and indirectly measure its density. The displaced water is how much water the object pushes away when it is gently placed into a cup (or beaker or graduated cylinder) of water.
It is most easily measured with a graduated cylinder by looking at the numbers along the side. Fill the cylinder part way and write down how much water is in it. Then gently put the object in the water. Write down how high the water now goes. The difference is the displaced water, and is also the volume of the object in the water.

When you place an object in water, it displaces (move away for the object to take up space in) the water. In order for said object to float on the water, the water that is displaced must have more weight than the object displacing the water. Since 1 cubic foot of water weighs about 64 pounds, the math from there is easy. Something that displaces 100 cubic feet of water must weight less than 6,400 pounds to float, or it sinks. Or to figure the inverse, if you had a 10,000 ton ship (20,000,000 pounds) divide 20,000,000 by 64 and you can see that the vessel must displace at least 312,500 cubic feet of water to float.

if you put something in a cup of water the diplaced water is the difference between the height of the water where it originally was and its new position. y2-y1
