Chapter 5, Problem 5.5P

Interpretation Introduction

Interpretation:

The height of column of water (mm ${\text{H}}_{\text{2}}\text{O}$ ) in tube should be calculated.

Concept Introduction:

The force which is exerted by a gas on the walls of the container is known as pressure of a gas.

The pressure which is exerted by the weight of the air above it at any point on the surface of earth is known as atmospheric pressure. The atmosphere supports a mercury column about 760 mmHg at sea level.

The formula which is used to calculate the height of column of water is:

  $\frac{h_{{\text{H}}_{\text{2}}\text{O}}}{h_{\text{Hg}}}=\frac{d_{\text{Hg}}}{d_{H_{2}O}}$

Where,

  $h_{{\text{H}}_{\text{2}}\text{O}}$ = height of column in water.

  $h_{\text{Hg}}$ = height of mercury.

  $d_{\text{Hg}}$ = density of mercury.

  $d_{{\text{H}}_2\text{O}}$ = density of water.
