Specific gravity of air (upper phase) (De Nouy ring method)

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)

$$ \rho_{\text {air }}=4.324 \cdot 10^{-2}\left(\frac{\mathrm{P}}{\mathrm{T}}\right) $$
