Key Features
- Two concentric tubes, copper inner tube for hot water and GI outer tube for cold water
- Arrangement supports both parallel-flow and counter-flow operation
- 4 thermometers measure inlet and outlet temperatures of both hot and cold streams
- Measuring flask allows accurate flow rate determination
- 3 kW geyser provides a controlled hot water supply
- Enables calculation of heat exchanged, LMTD and heat exchanger effectiveness
Applications
The Concentric Tube Heat Exchanger is used in heat transfer laboratories to study double-pipe heat exchanger performance, helping students compare parallel and counter-flow arrangements and calculate heat duty, log mean temperature difference (LMTD) and effectiveness.
