Technical Description
The benchtop unit provides clear demonstrations of condensation processes in a glass cylinder. The system has one condensation pipe with a polished gold-plated surface for dropwise condensation, and one condensation pipe with a matt surface for film condensation. The condensers are water-cooled. The cooling capacity can be determined. Sensors provide all relevant data which is indicated on digital displays. The measured values can, at the same time, be transmitted directly to a PC using a data acquisition card and analysed on the PC using the software supplied.
A supply of water is required.
Learning Objectives / Experiments
· Dropwise and film condensation
