• The unit allows students to perform the following experiments:
  • Measurement of pressure loss for laminar and turbulent flow.
  • Determination of critical Reynolds number.
  • Head loss measurements using tube manometer and mercury U-tube manometers.



  • Inverted U-tube water manometer (0-500mm)
  • U-tube mercury manometer (0-500mm)

Water Storage

  • Adjustable Elevated cylindrical tank for constant head
  • Tank capacity: 1~1.8 Liter (level indicator included)
  • Maximum flow rate: 30 L/h

Test pipe

  • Length (nominal): >500mm
  • Bore (nominal): 3~4mm
  • Needle valve included to regulate flow rate

The unit is supplied with Operating and Experiment Manuals in English giving full descriptions of the unit, summary of theory, experimental procedures and typical experimental results.

Note: Mercury will not be supplied with the apparatus due to transport Regulations.

This Pipe Friction Apparatus has been designed for students  to measure pipe friction losses for laminar and turbulent  flows. For laminar flow study, an elevated head tank is used  for water supply, whilst for turbulent flow, the supply is from  the Hydraulics Bench using hoses with rapid action hose  coupling. Students may control the flow rate of water by  adjusting the flow regulator valve. Lab main water supply can  be used for laminar and turbulent flow. The test section is  connected to manometers via pressure tappings.
