$\%$ Density $k\frac{g}{m^{{?}^{{?}^{?}}}}3$

$\%$ Function

function $[$Rho$]=$ Dens $(P_{-}t,P_{-}s,H)$

$\%$ Convert pressure to pascals

P$\_$t$\_$Pa $=P_{-}t**101325$;$\%1$ atm $=101325Pa$

P$\_$s$\_$Pa $=$ P$\_$s $**101325$;

$\%$ Caluclate density

Rho $=\frac{P_{-}{t}_{-}Pa-P_{-}{s}_{-}Pa}{\frac{H}{3\mathrm{.}28}}$
