The air flow experimental unit designed to demonstrate measuring the air flow important characteristics such as the flow and pressure. The unit also allows to study the system characteristics and velocity profiles.

                                     
  • The experimental unit is used to perform a variety of experiments to study the steady, incompressible flow.
  • The unit includes mainly an external Pitot tube that is used to measure free jets and an inner Pitot tube that allows the investigation of the air flow in the pipe section.
  • The length of the pipe section and the inlet controls the formation of air flow, the air flow can be studied using a nozzle or an orifice plate.
  • The experimental unit is provided with an iris diaphragm which allows changing the diameter of the air flow.
  • The unit allows the investigation of the Pipe friction losses on various pipe fittings.
  • The unit is provided with up to 20 pressure measuring points which means that the pressure conditions along the measuring section can be determined.
  • The unit also includes a tube manometer that is used to measure the pressures and so to determine the pressure distribution and flow velocity.
  • The unit can be used with an optional Venturi tube to practically prove the continuity equation and the conservation of energy during a change in cross-section of the air jet.
  • The unit can also be used with the boundary layers measurement accessory on a flat surface in longitudinal flow.
  • The measured values are used to determine velocity distributions within the boundary layer and to represent the boundary layer thickness.
  • Calculation of the flow rate and the flow velocity
