A cannon fires a shell that causes a projectile to move down the barrel at a velocity of 740 m/s. What is the speed of the normal shock proceeding down the barrel in front of the projectile if the undisturbed air in the barrel is at 101 kPa and 20°C? How fast would the projectile have to be moving down the barrel if the velocity of the shock ahead of the projectile was 2.5 times the velocity of the projectile?

A piston cylinder contains 1.25 kg water at 25°C with a constant load on the piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The process continues until 85% of the initial mass has flowed out.
