a property of the fluid

always given by $${\left( {\gamma RT} \right)^{{\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}}}$$ where $$\gamma $$, $$R$$ and $$T$$ are respectively the ratio of specific heats, gas constant and temperature in $$K$$

always given by $${\left( {\partial p/\partial \rho } \right)_s}^{{\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}}.$$ Where $$P,$$ $$\rho $$ and $$s$$ are respectively pressure, density and entropy

always greater than the velocity of fluid at any location.
