Fire service pump operators must have an understanding of the many laws of science that govern the study of hydraulics and water supply in order to be able to handle the complex hydraulic problems that may arise in real world scenarios. Based on the Fire and Emergency Services in Higher Education (FESHE) model curriculum for Fire Protection Hydraulics & Water Supply, the third edition of Fire Protection Hydraulics and Water Supply effectively teaches hydraulics by systematically addressing the underlying science in a way that makes challenging subject matter easier to understand and retain. Readers will be introduced to the basic properties of water and laws of hydraulics and friction loss before learning to apply formulas to calculate flow, friction loss, nozzle reaction, and more. Additionally, readers will progress to learn about: Complex principles of pump operation, including conditions such as end thrust and radial hydraulic balance, the application of Newton's first law of motion as it applies to a kinetic energy pump, and the concept of Enthalpy. Various laws of physics, including Pascal's Principle, Bernoulli's Principle, and Newton's third law of motion as it applies to the concept of nozzle reaction. New and improved formulas for calculating gallons per minute, nozzle reaction, and more. Additionally, each chapter now includes: Fireground Fact boxes that provide real world context or additional information on important topics. Case studies that emphasize a law or principle presented in the text. Updated key terms, formulas, and end-of-chapter resources. ? Revision Notes Revised table 5-1 Table 5-1 has been revised to include C Factors for all common smooth bore tip sizes. The C Factors are necessary for the version of Freeman's Formula used in the book for calculating flow from a smooth bore nozzle. The version of Freeman's formula used in Fire Protection Hydraulics and Water Supply, Revised 3rd Ed is the same one used in Section 15, Chapter 3, of the 20th edition of the Fire Protection Handbook, which is the current Fire Protection Handbook. No other current book on fire service hydraulics uses this version of Freeman's Formula. All other hydraulic books used a dumbed down version of Freeman's Formula that doesn't use C Factors. The C Factors in table 5-1 are used throughout the remainder of this book whenever the flow from a smooth bore nozzle is needed to solve a problem. Revised table 6-1 Table 6-1 contains Conversion Factors necessary when finding friction loss in various size hose. The revised Table 6-1 in Fire Protection Hydraulics and Water Supply, Revised 3rd Ed has added a third column with conversion factors to be used when calculating friction loss using the abbreviated formula, as explained in Chapter 6. The Conversion Factors from table 6-1 are used throughout the remainder of this book whenever FL 100 must be calculated.
