    Need help with method for fourth order DE

    I was given a 2 part example in class to work on for next class. 1) given the equation y'' + 3y' + 2y = 4 ; Initial conditions are y(0) = y'(0) = 0 I had no problem solving the DE, my result is as follows y=-4e^(-t) = 2e^(-2t) +2 2) given the equation y'''' + 3y''' + 2y'' = 4 ; Initial...

    Archived Adiabatic expansion in a steady flow question

    I an working on a problem in the text "Mechanics and Thermodynamics of Propulsion" 2e. The problem states a perfect gas with molecular weight M=20 and a specific heat ratio of Y=1.2 expands adiabatically in steady flow from a pressure of 6MPa, a temperature of 3000K, and a velocity of 200 m/s...
