Theory
This method of transferring
levels is based on the principle that a liquid always maintains it’s level.
Item required
Plastic tube, water
Procedure
Before starting the experiment
the tube is first filled with water upto about ¾ th of the actual length by
keeping the thumb on the one end of the tube. The level is marked. Before this
the height is marked at which we wants to transfer the level. The height is
then marked by chalk, keeping the one end of the tube is such a way that the
water level tube must be coincide with the point at which the levels are taken.
Then the another end of the water tube is lowered or rised in such a manner
that the height of the water in the tube should not disturb from its original
position. In this way the another point is marked. This point is a perfect
horizontal line.

Precaution
1. Clear
plastic water tube should be used.
2. There
should be no bubble in water tube.
3. Water
should be clean.
4. Thumb
should be kept on the end of the tube to avoid out going of water while
transferring level.
5. Water
tube should not be filled completely.
