The present set-up is designed to study the heat transfer in parallel and counter flow in concentric tube heat exchanger. Hot water flows through inner tube, coldwater flows through the outer tubes and can be operated in parallel or counter mode with respect to hot water.For hot water, a recirculating type water bath having PID temperature controller and a magnetic pump is provided. The flow rates are measured using flow sensors. Thetemperature of hot and cold fluids at inlet and outlet of heat exchanger can be measured by Temperature transmitter. It has an interfacing unit designed by  Engineers along with Lab view software. This educational software allows/enables user to log the real time experimental data and tabulate the experimental/sample reading according to the requirement of experiment. User have a control on data logging, printing the stored data and preparing spread sheets in Excel. Flexible graph plotting facility is also available in the software.

• An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.
• The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.
