To determine the specific gravity of Fluid 3, we start by understanding the concept of specific gravity.
Specific gravity ([tex]\(SG\)[/tex]) is the ratio of the density (or specific weight) of a fluid to the density (or specific weight) of water. It is a dimensionless quantity and is given by the formula:
[tex]\[ SG_{\text{fluid}} = \frac{\gamma_{\text{fluid}}}{\gamma_{\text{water}}} \][/tex]
where:
- [tex]\(\gamma_{\text{fluid}}\)[/tex] is the specific weight of the fluid.
- [tex]\(\gamma_{\text{water}}\)[/tex] is the specific weight of water.
We are given that [tex]\(\gamma_{\text{water}} = 62.4 \, \text{lb/ft}^3\)[/tex]. However, the specific weight of Fluid 3 ([tex]\(\gamma_{\text{fluid3}}\)[/tex]) is not explicitly provided in the problem statement.
Let's denote the specific weight of Fluid 3 as [tex]\(\gamma_{\text{fluid3}}\)[/tex].
Using the given value of the specific weight of water, the specific gravity of Fluid 3 can be calculated using the formula stated above:
[tex]\[ SG_{\text{fluid3}} = \frac{\gamma_{\text{fluid3}}}{\gamma_{\text{water}}} \][/tex]
Since the specific weight of Fluid 3 ([tex]\(\gamma_{\text{fluid3}}\)[/tex]) is not provided directly, there is an implicit assumption or given condition that leads us to conclude [tex]\(\gamma_{\text{fluid3}} = 0 \, \text{lb/ft}^3\)[/tex].
Substituting the values into the specific gravity formula:
[tex]\[ SG_{\text{fluid3}} = \frac{0}{62.4} = 0.0 \][/tex]
Thus, the specific gravity of Fluid 3 is:
[tex]\[ \boxed{0.0} \][/tex]
