Description

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
