Plumbing Math Workbook

About this book

This workbook is for plumbing apprentices, pipefitters, trade-school students, helpers and anyone studying for a plumbing exam who wants to get faster and more confident with the math of the trade: measuring and cutting pipe, figuring offsets, setting drain fall, working out pressure, volume and water heater recovery, and pricing a job. Each unit starts with a short lesson: what the math is, why it matters on the job, the formulas you need and one or more worked examples that show every step.

• A short lesson and worked examples at the start of every unit
• Practice problems drawn from real jobsite situations
• A full answer key, with every answer calculated and checked by computer

For practice and study. Always follow your plans, manufacturer instructions, local codes and your instructor or supervisor.
