. B Shadowgraph of shockwave for A 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. O 0.75 O 0.69 O 0.48 O 1.73Estimate the temperature at Point A just downstream of the shock wave shown in the figure above. O 366 K O 218 K O 393 K 300 KEstimate the pressure at Point A just downstream of the shock wave shown in he figure above. O 2.56 kPa 101 kPa 160 kPa 260 kPa
