PARALLEL FLOW/ COUNTER FLOW HEAT EXCHANGER APPARATUS

Product Description

Specification:

PARALLEL FLOW/ COUNTER FLOW HEAT EXCHANGER APPARATUS

Heat exchanger is devices in whichheat is transferred from one fluid to another. The apparatus consists of aconcentric 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 can bechanged from parallel or counter to hot water so that unit can be operated asparallel or counter flow heat exchanger. Flow rates of hot and cold water aremeasured using Rotameters. A magnetic drive pump is used to circulate the hotwater from a re-cycled type water tank, which is fitted with heaters andDigital Temperature Controller.

Experiment:

To calculate the following parametersboth for parallel and counter flow arrangement.

To find the rate of heat transfer

To calculate the LMTD Overall heattransfer co-efficient.

To compare the performance ofParallel and Counter flow heat exchanger

Utilities Required:
