Homework Help: Relaxation time approximation and ideal hydrodynamics

  1. Dec 21, 2014 #1
    1. The problem statement, all variables and given/known data

    please check attachment

    2. Relevant equations

    please check attachment

    3. 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
