Water Hammer Apparatus
Model Number: TE86
Demonstrates water hammer, cavitation, and shock-wave propagation in a water-filled pipe.
Overview
Demonstrates water hammer and cavitation and the propagation of shock waves at sonic velocity in water. The apparatus is made up of a coil of copper pipe 60 m long. The inlet connects to your water supply and the discharge end has a solenoid valve. An electronic pressure transducer near to the valve measures the pressure fluctuations in the pipe when the solenoid valve shuts. A bypass valve discharges to waste at the inlet end of the pipe. A second adjustable valve is at the discharge from the pipe, downstream of the solenoid valve. This regulates the mean pressure in the pipe before the solenoid valve shuts. A Bourdon pressure gauge fitted between the solenoid valve and the downstream control valve shows the pressure in the system. It also allows students to calibrate the pressure transducer.
