The unit is to determine Heat transfer rate, heat transfer coefficient, LMTD & effectiveness of heat exchanger in laminar as well as turbulent flow of air. A m..s. shell,in which copper tubes are fitted, baffle in the end box make the tube arrangement two pass type. Cold fluid is air enters the shell and flows over the tube. Hot fluid is water obtained from geyser & flows through the tubes. 25% cut baffles are provided in the path of air. Measuring tank for water flow rate, Orifice with water manometer for airflow, thermometer for inlet and out let temperature. |
