Chapter 3, Problem 3.2P

Interpretation Introduction

(a)

Interpretation:

Calculate the densities in $l{b}_m/f{t}^3$ using (i) conversion factors (ii) given equations.

Concept introduction:

The units can be converted as:

$\begin{array}{l}1l{b}_m=0.45359kg\\ 1f{t}^3=0.028317m^3\end{array}$

Interpretation Introduction

(b)

Interpretation:

Calculate the densities in $l{b}_m/f{t}^3$ of a solid with a specific gravity of 5.7. State your assumptions

Concept introduction:

The specific gravity is defined as:

$Thespecificgravity=\frac{Densityofthesolid}{Densityofwater}$
