Present set-up is computer controlled with data logging facility. When the equipment is interfaced to computer, the end user has an access of every input and output of the setup and can log data of experiments. The setup is designed to study the heat transfer in a pin fin. It consists of pin type fin fitted in a duct. A fan is provided on one side of duct to conduct experiments under forced draft conditions. Air flow rates can be varied. Measurement of air flow rate is done with the help of Differential manometer. A heater is installed at one of the Pin to heat. Heat input to the heater is controlled by computer signal to have a smooth control on desired temperature conditions as per end user requirements. This control facilitates end user to control required heat input to the heater, automatically, and further steady state of experiment is achieved in very less time as compared to manual control. Electronic energy meter will be provided to measure the heat input. It has an interfacing unit designed by Engineers along with Labview 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
