Hello Everyone,

 

This is a simple question. 

It is a shell&tube heat exchanger with steam on the shell side condensing and brine flowing inside the tube. My question is with a change in velocity on brine in the tube, lets say from 3ft/s to 5ft/s, will it improve the heat transfer coefficient? I believe it will, but I forget the theory behind it.

Thanks for any help.

An increase in liquid flow rate on the tube side will improve the heat transfer coefficient on the tube side. However, the overall heat transfer coefficient will not change much if the shell side coefficient is very much greater as is usually the case with condensing steam. Review the equations for heat transfer coefficient and how the individual coefficients are combined for an overall coefficient.

Hi,

You should refer to your textbook or notes from Uni.

Anyway, consider reading the document attached to support your query.

 

Good luck

but I forget the theory behind it.

It’s okay to not know the theory at the moment, but you need to know where to access the theory and utilize that knowledge. So, reference books, like uni heat transfer textbook, and other materials is critical.
