Water hammer and surge chamber, Investigation of formation, effect and function.

Features- visualisation of water hammer,-operation of a surge chamber,- determining the wave propagation velocity in water,- software for displaying the water hammer and oscillations. Learning Objectives / experiments. Transient flow conditions in pipe systems by means of experimentation,- demonstrating water hammer in pipes,- determining the wave propagation velocity in water,- understanding how a surge chamber works,- natural frequency in the surge chamber.

Specification:

• functioning of a surge chamber

• pipe section with ball valve and surge chamber

• surge chamber designed as transparent PMMA tank

• pressure sensor behind the water chamber for measuring the pressure wave

• pipe section with solenoid valve and two pressure sensors for measuring water hammer

• volumetric flow measurement via measuring tank of the supply unit
