A U-tube contains water and methylated spirit separated by mercury. The mercury columns in the two arms are in level with 10.0 cm of water in one arm and 12.5 cm of spirit in the other. What is the specific gravity of spirit?
Height of water column { h }_{ 1 } = 10.0 cm
Density of water = 1 g/ {{cm}^{3}}
Height of spirit column ({ h }_{ 2 }) = 12.5 cm
Density of spirit = ?
The mercury column in both arms of the U-tube are at same level, therefore pressure in both arms will be same. Pressure exerted by water column = pressure exerted by spirit column
