An explosion in the atmosphere (Patm = 101 kPa, Tatm = 20 degrees) instantaneously raises the static pressure at the explosion point to 1.42 MPa.

An explosion in the atmosphere (Patm = 101 kPa, Tatm = 20 degrees) instantaneously raises the static pressure at the explosion point to 1.42 MPa.a) Is the wave(s) generated a finite compression shock wave or a series of expansion waves?b) Assuming the waves(s) is locally planar, i.e the flow is normal to the waves(s), calculate the waves(s) velocity and static temperature, air velocity, stagnation pressure, and stagnation temperature behind the wave relative to the ground.
