This unit provides a recirculating water supply for a large range of TQ hydraulic experiments. The unit has been developed over a number of years to make the best use of modern materials, whilst retaining the best features of earlier models. The unit acts as a sump tank containing all the water necessary for the experiments, and the flat top of the unit provides an ideal working surface for the experiments.
The submersible pump provides a flow rate of approximately 60 litres per minute, which can be regulated using a modified control valve. Water flow passing through the experiment is measured by a gravimetric system, using a small inner tank, on a pivot arm, counter balanced by weights. By recording the time taken for the system to achieve balance, flow rate can be estimated to an accuracy of ±2%.

As part of a continuous programme of computerisation, many of these experiments are supplied complete with a dedicated TQ Computer Aided Learning Program consisting of a computer disk and a software manual. Each program provides both Tutorial (text) and Analytical (tables/graphs) sections thus leading the student clearly through the experiment and allowing data to be entered as the experiment proceeds. This data can be saved on disk for later analysis or printed for inclusion in laboratory reports. Automatic manipulation, reduction and printing of data in this way offers considerable reduction in laboratory time for both students and lecturers.
Supporting Teaching Material
A comprehensive laboratory manual covering the setting up and operation of the H1 Hydraulics Bench is supplied. A laboratory textbook entitled "A First Course in Hydraulics" by Professor E. Markland is also supplied free with this equipment.
A stopwatch such as the HAC10d is required to accurately time the water flow.
Sump tank capacity: 160 litres
Weigh tank capacity: 40 litres
Weights: 6 x 2kg
Pump: submersible type, 0-60 litre/min
A three wire single phase earthed mains supply,
220/240V 50Hz or
An earthed ground connection should be included for safety purposes. Please give full details of the required electrical supply when ordering the H1 Bench, i.e. voltage and frequency.
For satisfactory use of this equipment, a floor area of 2.5m x 1.5m is recommended. Experiments can be performed by students working singly or in groups of two or three.
