Description

The equipment is mounted on a free-standing framework which supports the test pipework and instrumentation.

The following typical pipe fittings are incorporated for study: mitre bend, 90° elbow, sweep bends (large and small radius), sudden contraction and sudden enlargement.

All are instrumented with upstream and downstream pressure tappings.
These tappings are connected to a bank of twelve water manometer tubes, mounted on the framework. Pressurisation of the manometers is facilititated by a hand pump.

A gate valve is used to control the flow rate. A separate gate valve is instrumented with upstream and downstream pressure tappings which are connected to a differential gauge on the edge of the framework.
