Product Description
PIPE SURGE & WATER HAMMER APPARATUS
- Self-contained unit designed to demonstrate the phenomenon of pipe surge and water hammer by gradual or fast closing of valves in the pipe line.
- Two separate stainless steel straight pipes with service module and Fluid Mechanics: Pipe Surge & Water Hammer constant head tank are used in this equipment.
- The pipe surge apparatus should employ a clear acrylic surge shaft to visualize and demonstrate gradual velocity or pressure rise and pressure oscillations due to the closing of valve slowly.
- A scale on the shaft to enable the amplitudes of the oscillations to be measured.
- Pipe surge resulting from gradual closure of valves causing changes in fluid velocity is clearly seen as change in the level in the surge shaft.
- A lever operated gate valve and a separate flow control valve should be mounted at the end of the test pipe.
- The Water Hammer Apparatus should employ a quick closing valve and a pair of pressure transducers which are mounted near the valve and far upstream.
- Water hammer resulting from the sudden closure of valve should be seen as a large increase in pressure and can be measured using pressure transducers.
- Analogue voltage outputs from these pressure transducers can be recorded for detailed studies.
- A Hydraulic Bench consisting of measuring tank, storage tank and centrifugal pump should be used to circulate water.
