Homework Statement

The Attempt at a Solution



since the deviation from f_0 to f is linear
then we can write f=f_0 + C where C is some constant
this should be enough to prove the first question (i think so)
for the second part i used the ideal gas equation to drive the partial derivatives with respect to time for density, velocity and temperature
but i couldn't able to get the answer[/B]

Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
