The apparatus is used for studying the heat transfer through a concentric tube under parallel or counter flow conditions.
The unit consists of a concentric tube heat exchanger, and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. Parallel or counter flow is by switching cold hoses valves. The unit requires outside water supply.
- Demonstration of heat transfer under parallel and counter flow.
- Determination of heat transfer coefficient.
- Effects of flow rate and temperature difference.
