Section 2 requires the ability to compute the volume
that an APEX must pump in order to move between two isobars: pi and
pf. The following expression applies,

Tf) are the in situ density and
temperature on isobars pi and pf, respectively. The profile below was
collected by APEX 231 and is useful for evaluating (12) at the
points located in Figure 1.
