Question

what is equiivalent height of water barometer if the pressure recorded by mercury barometer is 76 cm. Density of mercury is 13600 kg/m^3 and density of water 1000kg/m^3

Answer 1

Given :

Height of the column =75 cm = 75 × 10-2 m

Density of mercury = 13.6 × 10 3 kg/m 3

g = 9.8 m / s 2

After this please solve it

Answer 2

Answer:

For same pressure, ρ

1

gh

=1033.6cm

h
