Water Hammer Demonstration Unit: -The apparatus is designed to demonstrate shock waves in water at sonic velocity. Closing the pneumatic valve causes the pressure to rapidly attain a theoretical value and remain practically constant as the shock wave travels the length of the pipe, returning to the transducer as a negative pressure wave. The time required for the positive pressure wave to travel through the pipe is used to calculate the speed of sound in water. When the pressure attains the vapour pressure of the water in the conduit, it causes cavitation.
