Thank you so much! I truly appreciate your time. Yes there's an overwhelming amount of information on heat exchangers of course, I shall get to studying further!
I think the mechanical design and simulations will all be more straight forward once I get my numbers right, thanks again!
So this is what I get using inlet T of 25, 110 an outlet T of 70 and 85. I believed that the outlet T could be calculated by equating the q values but that gives me a negative value of T so I used 85 as a trial. The values are very different. I honestly thought this would be the easiest step of...
Thanks for your replies. My Q values are very far off, this is what's causing me the trouble. I have been determining cp values from the ideal gas heat capacity equation found in Chem Eng Design by Sinnot and Towler.
What do you mean by my data is inconsistent please? The mass balance across...
Thank you for your replies. I should have previously mentioned that I am a final year student, working on my design project. I feel that the mechanical design element will be rather easy, assuming values found in literature. The most basic step of determining Q is what I am struggling with...
Hi!
I'm currently in the process of designing a heat exchanger (as part of a large process). I know the desired inlet and outlet temperatures and the flow rates. Ethylene gas are the both streams being heated/cooled.
I am struggling to understand the difference between Q=m.c.dT and Q=U.A.dT...
