Question: A normal shock wave is propagating down a duct in which p = 120 kPa and T = 20 degrees Celsius. The pressure ratio

A normal shock wave is propagating down a duct in which p = 120 kPa and T = 20 degrees Celsius. The pressure ratio across the shock is 1.8. Find the velocity of the shock wave and the air velocity behind the shock. This moving shock strikes a closed end to the duct. Find the pressure on the closed end after the shock reflection.
