Inside Diameter calculate the circumference using the inside diameter plus the metal thickness. C = π × D D + thickness = 600 mm + 10 mm = 610 mm C = 3.14 × 610 mm = 1915 mm (rounded) C = 1915 mm Flat-out length is 1915 mm. 14″ Thickness ⅜″ 600 mm Thickness 10 mm Copyright Goodheart-Willcox Co., Inc.

Diagrams in practice problems allow extensive practice in real- world applications. Equations are presented throughout the text as examples and end-of-unit practice problems. When applicable, equations have arrows or carried over numbers in color to highlight the procedure for arriving at the answer. Unit Practice found at the end of each Unit includes a variety of exercises that allow ample practice in solving equations, understanding diagrams and dimensions, and applying knowledge gained in the Unit to situations that will be encountered on the job.
