DESCRIPTION :- Shell and Tube Heat Exchangers are popular in industries because they occupy less space and offer reasonable temperature drop. The apparatus consists of acrylic shell, inside which Stainless Steel tubes with baffles on outer side are fitted. This is single-pass heat exchanger so that hot water passes from one end of shell to the other end through the tubes. The cold water is admitted at the one end of shell, which passes over the hot-water tubes. Hot fluid flows in one direction only, whereas direction of cold fluid flow can be changed from parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. RTD PT-100 type temperature sensors are installed at various and appropriate locations to record the temperature of fluids at the time of running the experiment. This unit is an accessory of Heat Exchanger Service Unit and easily can be installed on the Service Unit.
EXPERIMENTATION :- To demonstrate the difference between parallel and counter flow operation. To study the temperature profile in parallel and counter flow heat exchanger.
