Objective
 To identify the different types of pipes,
fittings, valves and pump in a piping network
 To determine the pressure drop and thus the
friction coefficient for fluid flow through
different diameter tubes
 To make a friction factor chart using the data

Steps of Experiment
 Understand the piping network and determine the flow direction
through different diameter pipes.
 Connect the probes of the differential pressure meter to the pressure
tapings attached with a pipe.
 Allow water to flow only through that pipe.
 Note down the flow rate and pressure readings.
 Change the flow rate by controlling the inlet valve and take the
pressure reading for atleast four flow rates each in both laminar and
turbulent regime.
 Repeat the procedure for all the different diameter pipes and elbow
fittings.
