1. What two conditions are required of an ideal gas to have Tosy = Tosx across a normal shock wave?
2. The flow conditions just downstream of a standing normal shock wave in air in a wind tunnel are My = 0.500, py = 0.100 MPa, and Ty = 450. K. Determine the flow conditions just upstream of the shock (i.e., Mx, px, and Tx).
