Chapter 11, Problem 11.127QP

Interpretation Introduction

Interpretation:

The volume of air, pressure of the tire and the gauge pressure has to be calculated using the given condition.

Concept Introduction:

Boyle’s law states that the volume of a sample of a gas at constant temperature is inversely proportional to pressure

$\begin{array}{l}\text{V=}{\text{k}}_{\text{1}}\frac{\text{1}}{\text{P}}\text{(or)}\\ {\text{P}}_{\text{1}}{\text{V}}_{\text{1}}{\text{= P}}_{\text{2}}{\text{V}}_{\text{2}}\left(\text{at constant temperature}\right)\end{array}$

Pressure in the tire - atmospheric pressure = gauge pressure

Total force is the total of static pressure p, dynamic pressure q, and gravitational head.  Whole force is the calculate of the whole power of the airstream, and is equal to static force plus velocity force. The total force is the amount of the static and dynamic pressures.
