Working Principle
The apparatus operates on the principle of fluid flow through pipes where friction between the moving fluid and pipe surface causes head loss. Water is circulated through different pipe sections and fittings, and the pressure drop across the test section is measured using manometers or pressure gauges. The experimental results are used to determine friction factors and analyze flow characteristics under laminar and turbulent conditions.
The apparatus is suitable for experiments on:
- Friction loss in straight pipes
- Determination of Darcy friction factor
- Losses in bends, elbows, and valves
- Laminar and turbulent flow studies
- Verification of hydraulic flow equations
