SHELL & TUBE HEAT EXCHANGER APPARATUS-

Experimentation:

1. Determination of heat transfer coefficient for   inner and outer surface of tubes.
2. Study of variation of heat transfer coefficient with the type of flow.

Descriptions:

1. Shell and Tube Heat exchanges are popular in chemical industries because they occupy less space and offer reasonable pressure drop. The apparatus consists of fabricated M.S. Shell, inside which copper tubes with baffles on outer side are fitted. Hot water is obtained from a hot water tank provided in the setup. This is a two pass heat exchangers so that hot water passes to one end of shell through the tubes and returns to another end through remaining tubes. The cold water is admitted at the bottom of shell, Which passes over the hot‑water tubes. Control valves are provided to control the flow rates of hot and cold water and flow rates are measured with the help of measuring tank.
