Water hammer in pipes: Water hammer as a function of valve closing time; calculation of the wave propagation velocity in water.

Features- investigation of water hammer and pressure waves in pipes,- 60m long pipe section,- determining the wave propagation velocity in water,- solenoid valve with adjustable closing time,- software for displaying the pressure curve. Learning objectives/experiments,- water hammer as a function of flow rate,- water hammer as a function of valve closing time,- display pressure curve,- determine reflection time,-calculation of the wave propagation velocity in water.

Specification:

• investigation of water hammer and pressure waves in pipes

• pipe section as coiled tube to save space

• generation of water hammer via solenoid valve with constant closing time

• generation of water hammer via solenoid valve with adjustable closing time

• pressure vessel with air cushion reflects the wave

• safety valve protects against overpressure in the system
