HM 143 Transient Drainage Processes In Storage Reservoirs Demonstrational Equipment Vocational Training Equipment Fluid Mechanics Lab Equipment
Demonstration of the function of a rainwater retention basin and a storage lake
Features
– investigation of transient drainage processes in storage reservoirs
– simulation of rainwater retention basin and storage lakes
– transparent surge chamber for observing oscillations after a water hammer
– software for displaying the water levels
Learning objectives/experiments
– demonstrating transient drainage processes in two rainwater retention basins located one behind the other
– demonstrating transient drainage processes in two storage lakes located one behind the other
– recording oscillations of the water level in a surge chamber after water hammer
– recording and displaying water level fluctuations
Specification
[1] transient drainage processes in storage reservoirs
[2] functioning of a surge chamber
[3] “rainwater retention basin” experiment: basin A and basin B as short-term storage reservoirs, rectangular weir as gate
[4] “storage lakes” experiment: basin A and basin B are used as long-term storage reservoirs, rectangular weir as overfall weir
[5] “surge chamber” experiment: transparent pipe as surge chamber in drainage line of basin B
[6] gate in the drainage line for generating water hammer
[7] pressure sensors at both basins and the surge chamber capture the water level fluctuations
[8] representation of the variation in the water levels with software
[9] software for data acquisition via USB under Windows 10
