Transient drainage processes in storage reservoirs 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 - GUNT 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 GUNT software [9] GUNT software for data acquisition via USB under Windows 10 Technical data Basin A: LxWxH: 900x900x300mm - material: stainless steel - rectangular weir according to Rehbock, adjustable -- as gate, gate opening: 0...200mm -- as weir, weir height: 0...200mm -- overflowed width: 60mm Basin B: LxWxH: 900x900x300mm - material: stainless steel - overflow: 200mm Surge chamber - material: PMMA - Ø inner: 62mm - height: 1800mm Measuring ranges - pressure: 2x 0...100mbar, 1x 0...200mbar - flow rate: 300...3300L/h 230V, 50Hz, 1 phase 230V, 60Hz, 1 phase; 120V, 60Hz, 1 phase UL/CSA optional LxWxH: 1040x1220x2100mm Weight: approx. 165kg
