Considering the Code 5 in Kundu et al., for solution of one-dimensional compressible Euler Equations, add the capabilities to the code for obtaining: a) The plots shown in Fig. 6-26 plus the converged specific energy values along the length of the tube. b) Plots of Mach number, density, internal energy and pressure variation in time at user- selected grid points. Re-run the code and submit the modified code and the obtained plots. Show the modifications made and discuss the results. 0.8 0.6 0.4 0.2 0 300 250 Velocity 200 150 100 50 2 0 FIGURE 6.26 2 4 4 Density 6 6 8 8 10*10* 10 8 6 4 2 10 0 0.8 0.6 0.4 0.2 0 2 Mach Number 2 4 6 Pressure 4 6 8 8 10 10
