Description
The present setup is designed to study the friction head losses through pipes. fittings. and flow metering devices. Four different ID sizes smooth pipes and one artificially roughened pipe is connected in parallel. A valve arrangement is provided to operate the one pipe at a time. Various types of fitting are also fitted with pressure taps to conduct the experiment. Venturi meter. orifice
meter and pitot tube also accompanies the set-up. To measure the pressure difference across the each fitting. pressure taps are taken to manometer with help of no spill quick release couplings. Present set-up is selfcontained water re-circulating unit. provided with a sump tank. centrifugal pump etc. Water is pumped by means of centrifugal pump and passing through the selected test sections. it returns back to the sump which make the system re-circulating type. Flow of water is diverted either to measuring tank or sump tank with the means of a flow diverter. when needed. Flow control valve and bypass valve are fitted in water line to conduct the experiment on different flow rates. Flow rate of water is measured with the help of measuring tank with piezometer and stopwatch. The supplied set-up is complete in all respect. Only water supply and electricity
supply is to be provided by the end user for running the set-up.

To determine the head loss associated with flow through pipe fittings.
To determine the relationship between pipe friction coefficients and Reynolds number for flow through a pipe with roughened bore.
To study the differential head devices for measurement of flow rate and velocity.
