Question

ts on density and pressure imposed by the different energy condi- tions on a perfect fluid of equation of state p - wp where w is a constant. (b) What is the speed of sound of the fluid with equation of state ?-up? Hint: the speed of sound can be computed from the equation of state through dimensional analysis p is an energy density and p is a pressure. (c) From the previous parts, you already have the possible values of the speed of sound allowed by the energy conditions. Which ones are compatible with the speed of sound in the fluid being subluminal?

Explanation / Answer

If dnsity increases, state of the fluid tends to change.

Speed of sound is 310m/s

Normally in general conditions scramjets are more conpatible
