Chapter 4, Problem 22E

Interpretation Introduction

Interpretation:

The pressure of a gas contained in a mercury manometer is to be calculated.

Concept introduction:

A manometer is a device used to measure the pressure of the gas filled inside it, using the height of the mercury column inside the tube. In a closed-end manometer, the pressure on the mercury inside the tube is exerted only by the gas filled inside the tube. In an open-end manometer, the pressure is exerted on the mercury both by the atmosphere and by the gas filled inside the tube.
