How to draw a CAD diagram of a tube-type heat exchanger?

Thread Content

To draw an assembly diagram, what data is needed? Is there a template that guides you step by step? Please help

Also, the actual heat transfer area calculated is larger than what was estimated – is there a problem with that?

What is it based on for the estimate? Based on what is it calculated? How much less?

First, the overall heat transfer coefficient is estimated; then the heat transfer coefficients for the tube and shell sections are calculated, and from these the overall heat transfer coefficient is determined. The actual heat transfer area, as estimated, is 11.2, while the calculated value is 10.99
