The pipe friction for laminar/ turbulent flow (FM113) is a benchtop unit that is used to investigate pipe frictional losses with laminar and turbulent flows and allows determining the pipe friction coefficient factor.

  • The pipe section is a pipe with an internal diameter of 5 mm.
  • The distance between the pressure measuring fittings and thus the length of the experimental pipe section is 600 mm.
  • The pressure losses for laminar flow are measured using a water manometer.
  • The static pressure difference is displayed. A head tank is available to create a laminar flow and ensures a constant water inlet pressure in the pipe section at a constant water level.
  • For turbulent flow, the pressure difference is measured using a dial manometer. The head tank is not used to create a turbulent flow.
  • The experimental unit is positioned easily and securely on the work surface of the Main Hydraulic Unit that acts as the supply of water to the unit.
  • The water is fed directly into the pipe section from the water supply via a bypass.
  • The flow is adjusted using shut-off valves at the beginning and end of the pipe.
