The air in a laboratory reservoir is maintained at 20°C. It flows out through a converging-diverging nozzle into the laboratory maintained at 100 kPa, through a shape like that sketched in Fig. 4.66. Estimate the maximum velocity at the exit assuming an adiabatic, quasi-equilibrium flow with constant specific heats and a reservoir pressure of
a) 600 kPa,
b) 800 kPa,
c) 1200 kPa.
