In our lab class we are working with a heat exchanger. Its a single pass co-current system. The shell side fluid is steam and the tube fluid is water. The problem is that when the steam passes through the system the inlet temperature is lower than the outlet temperature. I was wondering if anyone had ideas as to why this was occurring?

Thanks

Dear fsustudent Hello/Good morning,
Some how your query seems incomplete 'as if this is a theoretical model case' or an exchanger in real physical existance.
I assume if there is a real life scenario then; unless sensing device is
working properly and
located adeqately this problem is inevitable.
hope this helps
