For the shock tube in Prob. 7.10, the lengths of the driver and driven sections are 3 and \(9 \mathrm{~m}\), respectively. On graph paper, plot the wave diagram ( \(x t\) diagram) showing the wave motion in the shock tube, including the incident and reflected shock waves, the contact surface, and the incident and reflected expansion waves. To construct the nonsimple region of the reflected expansion wave. Use at least four characteristic lines to define the incident expansion wave, as shown in Fig. 7.16.

Data From Problem 7.10:

The driver and driven gases of a pressure-driven shock tube are both air at \(300 \mathrm{~K}\). If the diaphragm pressure ratio is \(p_{4} / p_{1}=5\),
