Re: VFT tube leak

Fred, The there is about a full page of text that further explains the ifs and buts of the tube wall graph I posted. You're examples and graphs say the same thing in and easier to understand. Now that said, I think there is a miss type with 210c and 0.42bar, looking at the steam tables reveals 110c ...
