A Shadowgraph of shockwave for sphere traveling at Ma = 1.53 (taken from Shahriar Thesis, 2015, Florida State University) The figure above shows a shadowgraph of a shock wave created by a sphere traveling at Ma = 1.53 through air at 20 °C and 1 atm. Estimate the Mach Number at Point A, immediately downstream of the shock. 0.75 0.69 0.48 1.73 Estimate the pressure at Point A just downstream of the shock wave shown in he figure above. O 2.56 kPa O 101 kPa O 160 kPa O 260 kPa Estimate the temperature at Point A just downstream of the shock wave shown in the figure above. 366 K 218 K 393 K 300 K
