FLUID FRICTION MESURMENTS

Specification:

• System is mounted on a supporting rigid structure mounted on wheels.
• The flow velocity is measured using Floor Mount Type Parallel Pipes 'T'& 'Y' Junctions Fluid Mechanics: Friction Loss in Pipes Apparatus the calibrated variable area flow meter and the measuring tank of the Hydraulic Bench.
• The head loss due to friction should be measured using a suitably placed static pressure tapings, multi-tube manometer and digital pressure meter.
• Flow velocity or Reynolds number can be varied.
• A system of parallel pipe network configuration and isolating valves enable tests to be conducted on different pipes without disconnecting or draining the system.

Experiments:

• Familiarization and training with pressure and fluid flow measurements.
• Study of pipe friction at various flow velocities.
• Study of pipe friction in laminar and turbulent flows.
• Study of effect of surface roughness on friction factor.
• Determination of relationship between pipe friction factor and flow Reynolds numbers.
• Comparison of measured friction factors with Moody's chart.

Specifications:

The Apparatus should include the following pipes for testing:

• Smooth bore pipes: 27, 14 and 3.5 mm bore, 1800mm length, PVC.
• Artificially roughened pipes, 23 and 17 mm bore, 1800mm length, PVC. Color coding for piping system will be selected to suit user requirements.
• Pressure tapping is by small ball valves with quick connections will be provided at inlet and exit. Pressures are measured using multi-tube manometer. Pressure taps are connected to a set of manifolds by flexible pressure hoses such that differential pressure across pipe length can be measured by opening valves without removing the hoses.
• Flow measurement using Variable Area Flow Meter and measurement tank of the Hydraulic Bench.
• Water Manometer with hand air pump, 8 tubes X 800 mm with 1mm reading.
• Mercury Manometer, 2 tubes X 500 mm with 1mm reading.
• Digital Pressure Meter.
• Electrical supply, 240 V, single-phase, 50 Hz.
