A stability analysis of flow over a flat plate tells you that the a Tollmien-Schlichting wave at 98 Hz has the following spatial wavenumber: ((83.09E-3) - (-0.8E-3)i) rad/mm Is this wave stable or unstable? (Enter 1 for stable, -1 for unstable)

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

What precautions should you take to prevent injuries when dealing with heavy loads?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
