3 Properties

The intensive specific properties are lowercase, the corresponding extensive properties are uppercase:

\begin{displaymath}
v=\frac Vm \quad u= \frac Um \quad h=\frac Hm \quad s= \frac Sm
\qquad V=mv \quad U=mu \quad H=mh \quad S=ms \quad
\end{displaymath}

Definitions of enthalpy and entropy:

\begin{displaymath}
h \equiv u + p v
\qquad
s \equiv \int_{\mbox{\scriptsi...
...}}
\left(\frac{\delta q}{T}\right)_{\mbox{\scriptsize rev}}
\end{displaymath}

Specific volume and density:

\begin{displaymath}
v = \frac{1}{\rho}
\end{displaymath}

Pressure and force:

\begin{displaymath}
F = p A
\end{displaymath}

Static pressure differences versus height $H$ (height also indicated by $Z$) differences:

\begin{displaymath}
p_A - p_B = - \rho g \left(H_A - H_B\right)
\end{displaymath}

Number of kilomoles:

\begin{displaymath}
\bar n = \frac mM
\end{displaymath}

where $M$ is the molecular mass (table A.5.)
