Losses Due to Pipe Fittings, Sudden Enlargement

Category:

The present set-up is designed to study the pressure losses due to pipe fittings installed in pipe lines. It consists of a bend, elbow, a sudden expansion & contraction, ball valve and gate valve. Pressure tapings are provided at inlet and outlet of these fittings to measure the pressure difference using pressurized differential pressure manometer. Centrifugal pump is used to re-circulate the water from sump tank to the pipeline and is return back to the sump tank. Flow diverter is provided to divert the flow either to measuring tank or sump tank. Experiments can be conducted on different flow rates and measured with the help of measuring tank with piezometer and stopwatch.
