Question

the liquids shown in figure in the two arms are mercury(specific gravity 13.6) and water. If the difference of heights of the mercury columns is 2cm. Find the height of the water column

Answer 1

Explanation:

As, we know that pressure at same level in same medium are same,

So,

Pressure at A=pressure at B

fwgh=f mmaxgH[H=2cm]

h=13.6×2cm

h=27.2cm

h≈27cm
