Question

calculate the pressure due to a water column of height 100 m ( g=10m/sec² and density of water 10³kg/m³)​

Answer 1

Explanation:

Pressure will remain same for both the liquids.

Hence, Pressure = ρ×g×h

ρ = density of the liquid

g = acceleration due to gravity

h = height of the column

⟹ρ

mercury

×g×h

mercury

=ρ

water

×g×h

⟹ρ

=13.6 h

mercury

=70

ρ

=952cm

Answer 2

Explanation:

And the final answer is 10^6 Nm^-2
