DESCRIPTION:

Heat exchangers are widely used in various industries. Finned tube Heat Exchanger is a Tube-in-tube type heat exchanger. The inner tube is of Stainless steel with fins on its outside surface. Hot water flows through inner tube and cold fluid flows through the outer tube. The flow rate of hot & cold fluid is measured with the help of rotameters. Inlet and outlet temperatures of fluids are measured with the help of digital temperature indicators. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital Temperature Controller.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
