Dropwise And Filmwise Condensation Apparatus With Data Logging Facility

Category:

The present set-up is designed to demonstrate and determine heat transfer co-efficient of two types of condensation. It consists of a compact glass cylinder fitted with Condensation tubes and whole assembly is fitted on a vertical frame. Steam generator with water level indicator is fitted at the backside of the cylinder and steam is fed to the cylinder directly. Two valves are fitted to control flow rate of water in individual tubes and measured by Flow sensors. Temperature transmitter and Pressure sensor monitors the temperatures and steam pressure respectively. A Digital temperature Controller is provided for controlling the temperature of Steam. Condensate is measured by a level sensor. 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.
