The pipes are supported on frames and use hand screw clamps to connect the surge and hammer components. The equipment comprises two stainless steel pipes, which can be used either for surge tests or for hammer tests.
Experimental Capability:
Measurement of the velocity of sound through a fluid in a pipe
Recording of hammer pressure profiles using the digital scope supplied
Investigating the effects of pipe hammer caused by a fast closing valve.
Demonstration of water level oscillations in the surge shaft.
Demonstration of frictional head loss between reservoir and surge shaft.
Measuring the pressure profile of hammer
Demonstration of pipe surge.
A free standing unit developed to demonstrate the phenomena of pipe surge & water hammer when connected to a Hydraulics Bench.
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.
Includes two separate stainless steel test pipes, both 3m long, constant head tank, slow acting valve, fast acting valve etc
Straight metal pipes used, rather than a coiled arrangement, to minimize distortion to the pressure profile
A transparent surge shaft (40 mm diameter and 800mm high) with scale allows transient water levels to be observed and timed
Pressure transients monitored using a PC (not supplied) using a USB connection from the pressure transducers (requires no external electrical supply).
