### Summary

This edition of Mathematics for Plumbers and Pipefitters continues to teach the essential math concepts that have made the book the outstanding reference in its field. A collection of modern fitting materials demonstrates the various math concepts, and the book emphasizes a problem-solving methodology that can be applied to both current and future materials and job situations in plumbing and pipefitting. Enhancements to the text include simplified explanations, new drawings, a new unit on calculating partial volumes in odd-shaped tanks, and a reworked unit on heat-loss calculations that has been revised to keep pace with modern heat-loss methods.
