Double-pipe exchangers minimum

Minimum Area. The limit of minimum network area is presented in References 2 and 3. If idealized double-pipe exchangers are used, a heat-exchange network having minimum area can quickly be developed for any In the limiting case, where all heat-transfer coefficients are assumed to be equal, the area for this network can easily be obtained from the composite streams by... 

The hot fluid in a double-pipe exchanger enters at 65°C and leaves at 40°C, while the cold fluid enters at 15°C and leaves at 30°C. Is the exchanger operating at counter or parallel flow What is the exchanger effectiveness if the cold fluid is the minimum fluid ...
