FL 09.1 – Water Hammer

This equipment is used to visualize and study the phenomenon of water hammer.

Description
The equipment is designed to study the pressure increase produced by varying the flow through a valve, and to observe the positive and negative water hammer produced because of an instantaneous closure of a valve.

Also, it can be studied the effects of a surge pipe in reducing overpressure / depressure from water hammer.

The data is studied on a LabVIEW software.

Learning Objectives
  • Study and display pressure increase produced by varying the flow path through a valve.
  • Study and visualization of the phenomenon of water hammer produced by the instantaneous closure of a valve.
  • Study and visualization of the phenomenon of water hammer caused by the unexpected shutdown of a pump.
  • Study and viewing the effects of a surge tank in the attenuation of water hammer.
  • Determining the speed of sound through water in a pipe.
  •  Determination of head losses in a pipe.
