TURBULENT FLOW APPARATUS
FEATURES
Determination of Velocity Profiles at different flow rates.
Determination of Settling Length.
Determination of Friction Factor.
Kinetic energy correction factor can also be studied.

DESCRIPTION
The apparatus consists of a circular pipe with pressure taps.
Steady flow is set up in the pipe with the help of a suitable pump.
Differential manometer mesures the pressure drop.
Pitot probe placed in the pipe measures the pressure and velocity.
The probe can be traversed over a diameter to determine velocity profiles.
A calibrated orificemeter fitted in the pipe gives the discharge and acts as a fitting to determine setting length.

RANGE OF EXPERIMENTS
Study of velocity profiles.
Study of settling length.
Determination of friction coefficient.

SPECIFICATIONS
Centrifugal pump with motor
Pitot tube.
Swivel joint.
Orifice.
Measuring Tank – 100 litre capacity.
Stop watch.
Manometer without mercury.

SERVICES REQUIRED
