here is my problem
i know the delta temperature i want my nylon to be. with that i can solve for a multitude of things. to start off, this will give me my heat that is required to leave the nylon.
however, something went wrong. i am attempting to cool nylon, through stainless steel, and with flowly water on the other side in a series of heat exchange plates.
the last part of the attachment shows that when two different calculations are taken place, a different number results (not good).
as well as my Nusselt number is way too low. it should be a min of 100.
any help would be greatly appreciated on what i did wrong?!
