The collection of technical articles written in a friendly first-person style is intended to help new graduates and practicing workers solve certain important mechanical engineering problems when no flesh-and-blood mentor is available. The first volume takes up hydraulics, pipe flow, industrial HVAC, and utility systems. Necessary Facts pages are printed in large type. Many diagrams and drawings are provided. A second volume is projected to consider slightly more advanced topics, including pipe stress and stain, jacketed pipes, and process piping specialties.
