WL 314.01 Parallel Flow Module Show data sheet (pdf file) Print page
Technical Description

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



* Completely pre-assembled experimental unit with
