Question

Calculate the height of a water column which will exert on its base the same pressure as the 70 cm column of mercury. Density of mercury is 13.6 g/cm^3.​

Answer 1

Solution :-

(continuing with cgs system data)

Pressure of mercury column is hdg

= 70 x 13.6 x g ……..(1)

Let the height of water column = H cm

Pressure of water column

= H x 1 x g …………..(2)

As per problem statement,

Hg = 70 x 13.6 x g

H = 70 x 13.6

H = 952 cm

H = 9.52 m
