WL 314.01 Parallel Flow Module
Education / GUNT Hamburg / Thermal Engineering and HVAC / Applied Thermodynamics /

The heat transfer in and around pipes can be investigated using the WL 314.01.

  The heat transfer from the pipe wall to the medium is observed. A ring heater simulates the flow inside the pipe, while a rod heater reflects the conditions in the flow around a pipe.

  The power and surface temperature of the two electrical heaters are measured and displayed on the base unit WL 314.


Learning Objectives / Experiments

- Consideration of the relationships between Nusselt, Reynolds and

- Determination of heat transfer coefficient
- Calculation of the air velocity
