HM 241

Principles of Hydraulics

Technical Description

The HM 241 is part of a series of units that enable experiments to be performed on flow processes with the aid of a computer. Here several areas of incompressible flows can be investigated. After the recording of a pump characteristic curve, experiments on the topics of pipe flow and flow in open flumes can be performed. Water flows through a Venturi tube, an orifice, a bend, or a kink. During this process the pressure loss is measured and compared with the flow through a straight pipe. On flumes experiments can be performed on the open channel and on a channel with weir structures. Two different weir structures are supplied.
The HM 240.01 Data Logging Unit is necessary for the operation of the HM 241 Computer Linked Hydraulics Bench. If power data is to be displayed, the HM 240.02 Digital Power Meter is required.

Learning Objectives / Experiments

The Computer Linked Hydraulics Bench facilitates, together with the HM 241.01 Electronic Level Gauge, qualitative investigations on the following topics:
· Investigation of the flow of water in an open flume
· Investigation of weir structures in an open flume
· Pipe flow
· Pressure measurements at an orifice and Venturi tube
· Pressure measurements at pipe elbows and bends
· Recording of a pump characteristic curve
