Need to know heat transfer coefficient/therm. conductivity of ss tank
(OP)
I'm trying to compare an overall heat transfer coefficient I have calculated for a SS vessel, based on various assumptions. Does anyone know what the heat transfer coefficient or thermal conductivity of a bare 316ss vessel is? Thanks.

If you are looking for a ball park number. I would say 70 Btu/hr*ft2*F or less. That would be for water flowing in the jacket and a liquid hydrocarbon in the tank. With the tank being agitated.
My gut feel only.

In another recent thread someone quoted 0.5 BTU/hrft2F.

This factor needs to be addressed with a greater degree of seriousness and a reasonable correlation with the fluid(s), with as well as without agitation, found.
Is there any info available online on the topic?
Is there any published material where an attempt has been made to estimate or evaluate U for an SS vessel?
Any pointers are most welcome from forum members.

From Perry VI, expressed in 9.5 Btu/(h.ft.oF), it is 9.5 at 100oC, rising to 12.4 at 500oC

Apart from the temperature, under what other conditions do you think are those figures of 9.5 / 12.4 applicable?
RE: Need to know heat transfer coefficient/therm. conductivity of ss tank
Panduru, please note these values are thermal conductivities (see the units) and are not, repeat not, heat transfer coefficients.

Of course, they are. :)

Now I suppose everyone is looking at the issue from the right perspective.

Once you have experimented you can calculate and validate you calculation approach,

@jesabell44: pl update us on your observations, thanks.
