HL 111 Fluid Friction Training Panel
Education / GUNT Hamburg / Thermal Engineering and HVAC / Heating and Ventilation in Buildings /

Terms such as the static pressure of a fluid at rest (hydrostatic pressure), static pressure of a flowing liquid or the pressure loss between two points can be demonstrated on this trainer.

  The trainer includes a transparent tank with a pipe section connected as a drain. The initial pressure is kept constant by the overflow in the head tank. The pressure at six distributed measuring points on the pipe section can be measured on a multiple tube manometer.

Learning Objectives / Experiments

- Hydrostatic pressure
- Pressure variation in flowing fluids
- Pressure loss

- Representation of pressure curves
