Energy Losses In Bends Apparatus .
Energy Losses in Bends and Fittings
equipment is mounted on a free-standing framework which supports the
test pipe work and instrumentation. The following typical pipe fittings
are incorporated for study: mitre bend, 90o elbow, sweep
bends contraction and sudden enlargement. All are instrumented with
upstream and downstream pressure tapping. These tappings are connected
to a bank of twelve water manometer tubes, mounted on the framework.
Pressurization 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.
