Fluid Flow in Shell and Tube Heat Exchanger

Fluid to be passed through the shell :
1. fluids of which pressure drop should be low
2. Highly viscous fluids
3. Fluids with exhibit a low heat transfer rate
4. Fluids which undergo the phase change

Fluids to be passed through the tube
1. Dirty fluids
2. Fluids at higher pressure
3. Corrosive fluids
4. Cooling water
