The present setup is designed and fabricated to study lagging phenomenon in pipes. It consists of three concentric pipes of small thickness as compared to diameter and closed with the help of two discs. Two different insulating materials fill the annuli between the cylinders. Inside the inner pipe, a Nichrome wire heater is placed axially. Temperature transmitters are fitted to measure the temperature of pipe walls for radial outward heat flow measurement. Electronic energy meter is 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.
