Explanation:
Operation of specific gravity meter is based on Archimedes' principle.
It states that when a solid body is suspended in a fluid it experiences an upward force which is equal to the weight of the fluid displaced by the submerged part of the body.
The depth is read off the scale, as shown in the figure below:
When submerged to the marking
The position of the marking of
Assuming that the
Let
Its volume which is also Volume of water displaced
As the tube is in equilibrium (upwards thrust
Weight of tube
Weight of tube
where
Now the meter floats with
Weight of the liquid displaced
We know that SG

Explanation:
We know that the density of water at
The given uniform tube of length 10cm has also sp.gravity 1.0.
If the area of cross section of the tube be
And its weight becomes
If it floats in water immersing x cm length in water,then weight of water displaced by it will be
By Archimedes principle
So
Again it floats in the given liquid keeping 6cm immersed.
So the weight of displaced liquid will be
,where
Now applying Archimedes principle we have
