Compressible Fluid with Fluid Compressibility not depending on pressure $\begin{array}{l}p\end{array}$ :

(1)	$\begin{array}{l}\displaystyle c(T, p) = c(T)\end{array}$

which is equivalent to:

(2)	$\begin{array}{l}\displaystyle \frac{\partial c}{\partial p} = 0\end{array}$

Not to be confused with Slightly compressible flow, which is popular concept in Pressure Diffusion modelling, and which can sometimes develop for Incompressible fluids.
