Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

Question

Handwritten -HT

Q1) The hotter fluid of a parallel flow heat exchanger decreases in temperature
from 200°C to 100°C and the cooler fluid increases from 40°C to 90°C. For the
same heat transfer, what is the percentage saving in area made by using
counter flow instead?

A heat exchanger is heating water on the tube side with steam condensing on the shell side. The water is entering at 45 0 F and exiting at 175 0 F. No instruments are available for measuring the tube side water flow but condensed steam from the shell side is being collected at a rate of 43 GPM. If the tube area of the exchanger is 350 Ft2 , and the overall heat transfer coefficient clean was 900 BTU/Hr.Ft2 F0, how much has the overall heat transfer coefficient changed, if at all? Note: Latent heat for water/steam at 212 0 F is 970 BTU per pound of water. A gallon of water weighs 8.34 lbs.
