FLUID FRICTION APPARATUS

TecQuipment?s Fluid Friction Apparatus allows students to
study flow, flow measurement techniques and losses in a
wide variety of pipes and fittings.
The equipment has three water circuits with instruments,
pipes and pipe system components. These allow students
to examine and compare the different component
characteristics. The Digital Hydraulic Bench (H1F, available separately) supplies the circuit
with a controlled flow of water. A space-saving vertical
panel holds all the parts for easy use.
To measure pressure loss across components, students use
a piezometer set and differential pressure gauge
(included).
To perform experiments students record the temperature
of water in the hydraulic bench and set the hydraulic
bench to pump water through a circuit. They measure
pressure losses across instruments or components. The
hydraulic bench gives an external flow rate for reference
and comparison.
The flow measurement instruments show students the
common methods of measuring water flow. They also give
applications of the steady flow energy equation (Bernoulli?s
equation). Students use a Venturi meter and an orifice
plate meter and compare the losses of each. They also find
the losses in a rapid enlargement.
The equipment also includes a Pitot-static tube. By
traversing the Pitot across the pipe diameter, students can
find the velocity profile and flow coefficients. They also
find the relationship between the flow rate and pressure
differential.
An artificially roughened pipe allows students to study
friction factor at different Reynolds numbers. They can
compare results to those predicted by Nickuradse?s results
and a Moody chart.
