## Student Learning Outcomes

• A successful student will be able to calculate pipe diagonals and derive pipe lengths.
• A successful student will be able to calculate elevation and grade.
• A successful student will be able to calculate rolling offsets.

## Description

Extensive use of piping formulas to solve typical piping layout calculations. Students calculate compound offsets and accurately determine center to center and end to end piping measurements for plumbing systems.

## Course Objectives

The student will be able to:

1. Demonstrate basic math skills using fractions, decimals, conversion tables, ratios, and compound measurements
2. Illustrate the use of engineering and architectural measurements
3. Calculate and lay-out a piping system using formulas, angles, symbols, and piping offsets
