Hi everybody,

I need to quickly estimate the geometry of a jacket for superheating anhydrous hydrogen chloride inside a pipe (assume high pressure gas).
Shell-side fluid will be hot water.

Can anyone of you suggest me an assumption for overall heat transfer coefficient U?

Thanks in advance for your cooperation!

A ballpark figure could be 0.2 kW/(m2 K).

Some tables I have of general overall heat transfer coefficients confirm what 25326 is saying. They state a range of 0.2-0.3kW/m2K

Goodluck

Thank you very much.

I found an additional reference stating a range of 0.2-0.4 kW/m^2*K, so I'll assume 0.2 to be conservative.
I guess this won't be far from the truth.

Appreciated your support, see you for the next one.
