3 Properties

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

$$v=\frac Vm \quad u= \frac Um \quad h=\frac Hm \quad s= \frac Sm \qquad V=mv \quad U=mu \quad H=mh \quad S=ms \quad$$

Definitions of enthalpy and entropy:

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

Specific volume and density:

$$v = \frac{1}{\rho}$$

Pressure and force:

$$F = p A$$

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

$$p_A - p_B = - \rho g \left(H_A - H_B\right)$$

Number of kilomoles:

$$\bar n = \frac mM$$

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