FM541 · Water Hammer in Pipes

Experimental Apparatus for the Study of Water Hammer in Pipes

Experiments
  • Water hammer as a function of valve closing time
  • Water hammer as a function of steady-state flow rate
  • Visualisation and measurement of pressure transients during water hammer
  • Determination of pressure wave reflection time
  • Calculation of wave propagation velocity in water
  • Modification of the valve closing law to prevent the onset of water hammer

Pressure vessel
air cushion — simulates open boundary, ensures clear wave reflection
Coiled copper pipe
33 turns · 60 m · coiling minimizes footprint while keeping full length for measurable reflection times
Pressure transducer
0…10 bar
Manometer
Solenoid valve
constant closing time (20…30 ms)
Solenoid valve
adjustable closing time (1…4 s)
Rotameter
up to 300 L/h
Safety valve
16 bar - protects against overpressure
