i'm a chemical eng. student from Italy and i'm "sizing" ("setting"?) a heat exchanger to cool some octane with toluene.
Is it possible that pressure drops shell side in a 1,2 pull-through floating head heat exchanger are lower than 0.001 atmosphere? I used really wide buffles and buffle cuts opened at 45%. The heat exchange is in range and the pressure drops tube side are "normal" (0.2 atm). I just find it weird that shell side they are so low. Can someone help me?
