Knowing the pinch temperature and the minimum utility targets tells you the best a design could achieve. Actually building a network of heat exchangers that hits those targets is the next step β and it turns out not every pairing of hot and cold streams is thermodynamically possible right at the pinch. This lesson gives you the rule that decides which matches work, and builds a complete, feasible network from it.
