An engineer of/in what?Your "certainty" is in error for the reasons I already stated.
That tube will never see but a fraction of that heat to start with then being the "cooler"- it will absorb and sink what it does absorb long before it transfers it to the contents. ( that's not even counting any fluid properties, specific heat, transfer coefficient of time or anything else)
The difference is I am an Engineer who does a good bit of heat exchange work in industry and don't need to link hunt to make my point without fully understanding the science represented in the link.
The list is perhaps then not for you, but the other readers who always demand a reference.
