Okay I have my first HX sizing for a homework problem, and I have h and k values so I can find overall U. The problem I'm having is the fact that I'm given little info for the the delta T, I'm told I want to vaporize 6,000lb/hr methanol by ping steam through the shell side of a double-pipe HX (both components are at atmospheric pressure and steam condenses through the HX). I can use a steam table, but what about the methanol? How am I supposed to find the temperature when it's entering the exchanger?
