Chapter 1, Problem 1.8P
Interpretation Introduction

Interpretation:

The absolute pressure reading on the mercury manometer in kPa under the given conditions should be identified.

Concept introduction:

The pressure which is exerted by a fluid having certain column height depends upon acceleration due to gravity and density of the fluid.

Pgauge = hρg ------(1)

Where, h = height of the mercury

ρ = density

g = acceleration due to gravity

The formula for absolute pressure is given as:

Pabsolute = Pgauge + Patm -------(2)

Where, Pgauge is pressure of gauge,

Patm is atmospheric pressure
