Chapter 9, Problem 9.32CP

Interpretation Introduction

Interpretation:

The way to read the gas pressure in the bulb of the given manometer has to be given.

Concept Introduction:

Manometer: Manometer is a device which consists of U-shape tube which is used to measure the pressure of the gas contained in a container that is closed.

$\text{Pressure}\text{=}\frac{\text{Force}}{\text{Area}}$

Pressure can be expressed in different units.  But it is normally reported in $\text{mm}\text{Hg}\left(\text{millimeters}\text{of}\text{mercury}\right)$

General unit conversions:

$1atm$ is equal to $760mmHg$

$1pascal$ is equal to $1newton/mete{r}^2$

$1bar$ is equal to $1\times 10^{5}pascal$
