Energy Losses in Bends and Fittings.
Energy Losses in Bends and Fittings
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, 90º 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 twelve water manometer tubes,
mounted on the framework. Pressurization 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. The unit stands on the working top of the
Hydraulics Bench which is also used as the source of water supply.
Experimental Capabilities:
Measuring the losses in the devices related to flow rate and calculating loss coefficients related to velocity head.
Comparing the pressure drop across each device.
