Heat conduction in fluids
Determination of the coefficient of thermal conductivity for gaseous and liquid fluids
Features

• effect of different fluids on heat conduction

• network capability: network access to ongoing experiments by any number of external workstations

• software: operation and control of the experimental unit, data acquisition and educational software

Specification

• investigation of the thermal conductivity of common fluids, e.g. water, oil, air or carbon dioxide

• concentric annular gap between 2 cylinders containing the fluid being studied

• inner cylinder, continuously electrically heated

• water-cooled outer cylinder

• display of temperatures and heating power in the software

• due to integrated microprocessor-based instrumentation no additional devices with error-prone wiring are required 

• functions of the software: system operation, data acquisition, educational software

• network capability: LAN/WLAN connection of any number of external workstations with software for observation and evaluation of the experiments 

• E-Learning: multi-media didactic materials accessible online

• software for data acquisition via USB under Windows 8.1, 10
