Pancake spiral coil in a vessel
Pancake spiral coil in a vessel
(OP)
Hello,
I need to calculate external heat transfer coefficient outside a horizontal pancake spiral coil placed in a vertical vesssel (a glycol dehydrator).
In addition to the correlation Nu = f(Re, Pr), i need to know:
1/ How to determine equivalent diameter outside the coil
2/ How to calculate the velocity through the coil
Could you please help me?
Any reference (book, article) will be more than welcomed.
Regards

How about the old standby, "Process Heat Transfer" by Kern on page 721.
