Plate type heat exchangers have less surface area as compared to a similar Shell and Tube heat exchanger. A Shell and Tube Heat Exchanger of equivalent area weigh six-seven times less than a Plate Type heat exchanger.

Plate type heat exchangers have less surface area as compared to a similar Shell and Tube heat exchanger. A Shell and Tube Heat Exchanger of equivalent area weigh six-seven times less than a Plate Type heat exchanger. Correct Answer False

Owing to the large number of plates that can be arranged parallelly to each other, Plate Type Heat Exchangers have a very large area for heat transfer and weigh very less (6-7times) than an equivalent Shell and tube type.

Air is to be heated by condensing steam. Two heat exchangers are available (i) a shell and tube heat exchanger and (ii) a finned tube heat exchanger. Tube side heat transfer area are equal in both the cases. The recommended arrangement is
The important design and operating considerations for Extended-Surface Compact Heat Exchangers are: (1) Both fluids may have high or low heat transfer coefficients (2) As the tubes are very narrow (low DH), the fluid used should not be corrosive as effective cleaning of tubes is not possible. (3) The fluid pressure drop calculation is important as a regulatory method to ensure long life of the tubes. (4) Unlike shell and tube type heat exchangers, these are limited when it comes to operating pressure and temperature.
A single pass shell and tube heat exchanger, consisting of a bundle of 100 tubes (inner diameter 25 mm and thickness 2 mm) is used for heating 28 kg/s of water from 25 degree Celsius to 75 degree Celsius with the help of a steam condensing at atmospheric pressure on the shell side with condensing heat transfer coefficient 5000 W/m2 degree. Make calculation for overall heat transfer coefficient based on the inner area. Take fouling factor on the water side to be 0.002 m2 degree/W per tube and neglect effect of fouling factor on the shell side and thermal resistance of the tube wall

Statement 1: Plate heat exchangers are used in heat sensitive foods like milk. Statement 2: Principle behind plate heat exchangers is that there is very less space between the plates and hence quick heating can take place.
