PARALLEL FLOW/ COUNTER FLOW HEAT EXCHANGER APPARATUS

Product Description

Heat exchanger is devices inwhich heat is transferred from one fluid to another. The apparatus consists ofa concentric tube heat exchanger. Hot water flows through inner tube in onedirection only and cold water flows over the inner tube in outer tube.

Direction of cold fluid flow canbe changed from parallel or counter to hot water so that unit can be operatedas parallel or counter flow heat exchanger. Flow rates of hot and cold waterare measured using Rotameters. A magnetic drive pump is used to circulate thehot water from a re-cycled type water tank, which is fitted with heaters andDigital Temperature Controller.

Experiment:
