F1-22 – Energy Losses in Bends and Fittings

 

F1-22 – Energy Losses in Bends and Fittings

This accessory permits losses in different bends, a sudden contraction, sudden enlargement and a typical control valve, to be demonstrated.

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, swept 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 12 water manometer tubes, mounted on the framework. Pressurisation of the manometers is facilitated 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. The unit stands on the working top of the Hydraulics Bench, which is also used as the source of water supply.

This accessory permits losses in different bends, a sudden contraction, sudden enlargement and a typical control valve, to be demonstrated.
