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. Condensation is a phase change heat transfer process occurring in many industrial applications, such as in steam power plants, refrigeration plants etc. Thus this is one of the important heat transfer process as present in mechanical and chemical engineering applications. The condensation of vapour on a surface is of two types: 1. Drop wise Condensation, 2. Film wise Condensation. This setup is designed for determining heat transfer co-efficient of two types of condensation and for visualization of these processes. It consists of a vertical frame. Condensation tubes are fitted inside compact glass cylinder. Steam generator is fitted at the backside of the cylinder. Steam comes directly from generator to the cylinder. Twovalves are fitted to control flow rate of water in individual tubes. A special arrangement is provided to control heat input to heater for controlling the temperature of Steam. 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.
