Question

What depth of mercury (in m) creates a pressure of 1.13 atm?

Answer 1

Given:-

• Pressure :
• Gravitational acceleration :
• Density of the mercury    :

We know that,

therefore,

Atmospheric pressure is defined as the force exerted per unit area by the weight of the fluid and is given by,

Where,

• : is the depth
• : is the acceleration due to gravity.

therefore,

or in two significant figure,

This is the required depth of mercury (in m).
