A single phase fluid

is to be cooled from 175°C to 75°C by exchanging heat with another single phase fluid

which is to be heated from 50°C to 150°C. You have the choice of one of the following five heat exchangers:

Which exchanger do you recommend using for this service? Carefully explain your answer.

(For the following problems and where information on organic materials is not given in the problem, the physical properties may be obtained from a process simulator using the SRK thermodynamics package or from using suitable handbooks.)
