Assumptions:
The default isobaric specific heat capacity (via bc = [935*U.J*Data.m/(U.kg*U.K)]
)
and thermal
resistivity (θ = U.m*U.K/(11.1*U.W)
) are for graphite fiber epoxy (25% vol)
composite (with heat flow parallel to the fibers) at 300 K
[Incropera2002, p. 909].
The integration offset for specific entropy is set such that
the specific entropy is 154.663 J/(mol·K) at 25 °C and po (1 atm).
This is the value from Table B in [McBride2002].
Additional thermal data is listed in Table 1.
