Students of mine (HS) are exploring the way to simulate a sonic boom at
low atmospheric pressure. The argument behind it is since the speed of
sound decrease with density, a sonic boom might be easier to simulate in
a lower pressure system.
We've look at one formula that gives a relationship between temperature,
density and speed of sound in air but couldn't find one with Pressure,
density and speed.
We've hit a wall...
Can the project be done ?
What is the relationship between Pressure-density-speed ?
What is the meaning of the 1.4 constant of air in the temp-density-speed
equation ?
