Chapter 10, Problem 16QP

Interpretation Introduction

Interpretation:

The height of the column of ethylene glycol is to be calculated.

Concept introduction:

The pressure applied by a fluid in a column can be calculated as follows:

$P=hdg$

Here, $P$ is the pressure, $h$ is the height, $d$ is the density, and $g$ is the gravitational constant.

The pressure exerted by a gas is the force per unit area and the symbol is $P$.

The S.I. unit of pressure is Pascal and the common units are atm, mmHg, torr, and bar.
