SUMMARY

The discussion revolves around the shell diameter correlations for ST-type heat exchangers, specifically referencing an equation from Ludwig's "Applied Process Design for Chemical and Petrochemical Plants," found in equation 10-2. The user initially struggled to locate this equation but ultimately identified it in a different Ludwig publication. This highlights the importance of consulting multiple resources when researching specific engineering equations.

PREREQUISITES
  • Understanding of ST-type heat exchangers
  • Familiarity with Ludwig's engineering texts
  • Knowledge of heat exchanger design principles
  • Basic skills in chemical engineering calculations
NEXT STEPS
  • Review Ludwig's "Applied Process Design for Chemical and Petrochemical Plants" for detailed equations
  • Study heat exchanger design methodologies and best practices
  • Explore shell and tube heat exchanger performance optimization techniques
  • Investigate correlations for shell diameter based on tube pitch and number
USEFUL FOR

Chemical engineers, process design professionals, and students involved in heat exchanger design and optimization will benefit from this discussion.

TL;DR
Formula for shell diameter.
Hello. I have figured out a few things about ST-type exchangers and I intend to build a reactor with this new knowledge. I have a rather... small problem.

So I searched for shell diameter correlations given the pitch and number of tubes and I found this from a writeup:

Apparently, it's from Ludwig, but the writeup did not say where the equation is, exactly. I have been staring and scanning at Ludwig for five long hours now and I am unable to find this equation (lol, I swear my eye nerves are going to burst). Is someone familiar with this equation? Thank you.

Nevermind, found it. Apparently it's in another Ludwig book. Applied Process Design for Chemical and Petrochemical Plants; eqn 10-2; for people who might need this.
