Input(s)
P: Pressure (psi)
\(\mathrm{T}\): Temperature \(\left({ }^{\circ} \mathrm{R}\right)\)
Output(s)
\(\rho_{\text {air }}\): Specific Gravity of Air at \(\mathrm{P}\) and \(\mathrm{T}\left(\mathrm{g} / \mathrm{cm}^{3}\right)\)
Formula(s)
\[
\rho_{\text {air }}=4.324 \cdot 10^{-2}\left(\frac{\mathrm{P}}{\mathrm{T}}\right)
\]
