4th Printing of the Book "Lessons in Wildland fire Hydraulics & Formulas". Book has been Updated, Revised and Edited. Now covers 148 pages total.

Includes Bambi Bucket cooling capacities for every bucket made. Includes a section on Fire Behavior Nomograms that explains how nomograms are used to determine a fires intensity in Btu. This section is absolutely vital to understand how thermal intensity is determined. If you cannot determine intensity you will not be able to determine how much cooling you need or how much fuel to remove, etc. This covers a section on fire thermodynamics that is simply not taught anywhere in the wildland fire training programs!

The Book Covers 14 lessons.

Lessons 1 & 2 cover Properties of Water and Calculating Heat Generation & Absorption.

Lessons 3 & 4 cover Centrifugal Pumps and Rules of Thumb.

Lessons 5 & 6 cover Pump Pressure Calculation and Head Pressure determination.

Lessons 7 & 8 cover Nozzle Pressures & Affinity Laws and the Fire Slide Rule use.

Lessons 9 & 10 cover Friction Losses for simple and Progressive Hose lays.

Lesson 11 is 11 pages and is dedicated solely to Drafting Principles and covers the technical elements that allow us to draft water to which many are simply NEVER taught. You will Never worry about being able to draft water again!

Lessons 12 - 14 cover Relay Pumping Operations, What your watchouts will likely be and how to plan for them. These lessons cover the 7 principle areas that must be considered before designing a relay operation, including showing you how to calculate the number of engines required for a relay as well as how to determine the spacing between each engine. However, the Relay Pumping system is nearly almost always either under or never utilized in the wildland fire service!
