Compressible Flow A converging-diverging nozzle operates at steady state. Air as an ideal gas with k = 1.4 enters the nozzle at 500 K, 6 bar, and a Mach number of 0.3. The air flows isentropically to the exit plane, where a normal shock stands. The temperature just upstream of the shock is 380.416 K. Determine the back pressure, in bar.
Shock 09/11/2015 ▯ Decreased tissue perfusion, imbalance of supply of oxygen and the demand of the body ▯ Stages of shock initial stage o usually not clinically apparent (body has been able to deal with the balance of supply of oxygen and nutrients) o metabolism changes from aerobic to anaerobic – causes a build up of lactic acid (body normally removes it in liver and blood) compensatory stage o Body tried to compensate for build up of lactic acid o attempt to overcome consequences of anaerobic metabolism to maintain homeostasis o dro
