Pipe Surge and Water Hammer Apparatus

Product Description

Pipe Surge And Water Hammer Apparatus MTFM-12

Pipe surge and water hammer are two related but independent phenomena which arise when fluid flowing in a pipe is accelerated or decelerated. The associated pressure transients can be damaging to pipe work or components and systems must be designed to avoid or with stand them.

The equipment designed by clearly demonstrates the different effects resulting from gradual or instantaneous changes in fluid velocity. Effect of initial fluid velocity can also be investigated. Pipe surge resulting from a gradual change in fluid velocity is clearly seen as fluctuating changes in head in a surge shaft.

DEMONSTRATION CAPABILITIES

• Demonstration of pipe surge
• Determination of oscillatory characteristics of the surge shaft
• Demonstration of frictional head loss between reservoir and surge shaft
• Comparison between theoretical and measured pressure profiles produced by water hammer
• Using a dual trace storage oscilloscope to record transient water hammer pressure profiles
• Measuring the pressure profile characteristics
• Determination of the velocity of sound through a fluid in a pipe
• Demonstration of the effects of cavitations on subsequent cycles.

TECHNICAL SPECIFICATIONS

• Pipe surge test pipe: stainless steel 22 mm I/D x 3 m long
• Surge shaft : clear acrylic 40 mm I/D x 800 mm H
• Service pump: centrifugal type, delivering 1.35 liters/sec at 3 m H20
• Flow rate measurement: volumetric tank, stepped 0-40 liter high flows 0-6 liter low flows
• Head tank: capacity 45 liters
• A self-contained unit designed to demonstrate the phenomena of pipe surge and water hammer.
• The unit includes two separate test pipes, service module and constant head tank.
• Two pressure transducers provide electrical signals for connection to a dual trace storage oscilloscope with an integral printer output.
• Straight pipes are used, rather than a coiled arrangement, to reduce distortion of the pressure wave.
