Pipe Surge and Water Hammer Apparatus
This device helps to determine the difference between phenomena of pipe surge and water hammer. It also determines that how it is created. The device consists of two test pipes. One test pipe is used for water hammer investigation and one pipe is used for surge investigation.
Specification:
- A freestanding unit designed to demonstrate the phenomena of pipe surge and water hammer when connected to a Hydraulics Bench
- Includes two separate stainless steel test pipes, both 3m long, constant head tank, slow acting valve, fast acting valve etc
- A transparent surge shaft (40 mm diameter and 800mm high) with scale allows transient water levels to be observed and timed
- Electronic sensors used to measure pressure transients at two locations in the water hammer test pipe, one adjacent to fast acting valve and one half way along the test pipe.
- Pressure transients monitored using a PC (not supplied) using a USB connection from the pressure transducers (requires no external electrical supply)
- Straight metal pipes used, rather than a coiled arrangement, to minimize distortion to the pressure profile
