Heat exchanger is a device in which heat is transferred from one fluid to another. The apparatus consists of a concentric tube heat exchanger. Hot water flows through inner tube in one direction only and cold water flows through the outer tubes. 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. Flow rates of hot and cold water are measured using Rotameters. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital


Temperature Controller.


EXPERIMENTATION-
-To calculate the Rate of Heat Transfer
-To calculate the LMTD.
-To calculate the Overall heat transfer co-efficient.
-To compare the performance of Parallel and Counter flow heat exchanger

The Unit consists of a strong cylinder containing fluid. A water cooled coil in the upper part of the
cylinder condenses the vapour and returns it to the boiling liquid. The condenser cooling water rate can
be measured and controlled also.


EXPERIMENTATION-
- To plot graph of heat flux & temperature difference between metal & liquid
-To calculate amount heat taken away by water from condensing vapour.
