HOW HYDRAULICS IS A NECESSITY WITHIN THE FIRE SERVICE 1 How Hydraulics is a Necessity Within the Fire Service Edubijen G Ramirez Elgin Community College Author Note Fire Protection & Hydraulics, Elgin Community College Correspondence regarding this article should be addressed to Edubijen G Ramirez, Elgin Community College, Elgin, IL 60123. Contact: eramirez9287@student.elgin.edu Abstract Hydraulics has been a part of the fire service since the beginning of time. Since the 1600’s of carrying water in buckets, to the design of the first pumper. Water is an essential element to us as humans and to make the world function. The core definition of Hydraulics in a dictionary is, “the branch of science and technology concerned with the conveyance of liquids through pipes and channels, especially as a source of mechanical force or control.” The science

HOW HYDRAULICS IS A NECESSITY WITHIN THE FIRE SERVICE 2 of hydraulics was paved through by individuals as Leonhard Euler, Daniel Bernoulli, and Blaise Pascal. We use the definition of the laws and principles we study today. Using the book ‘Fire Protection Hydraulics and Water Supply’, by William F. Crapo, Hydraulics is defined as the science of water (or other fluids) at rest and in motion. Hydraulics is an applied science, as opposed to a theoretical science in that it is a real-world application of well-established laws of physics. The science of hydraulics originally began as a study of water alone. It evolved into a deeper study of hydrostatics and hydrodynamics. Hydrostatics is the study of water at rest. Hydrodynamics is the study of water in motion. Scientifically hydraulics is seen in everyday life. An example is, at home your sink water is at rest without use and once you use it the water is in motion. Seeing the examples of hydraulics can visually teach you how we need hydraulics in real life. The application of hydraulic principles, from engineering to water supply needs, began in 1889. Engineers such as J. Herbert Shedd, J.T. Fanning, John R. Freeman, and Emil Kuichling, started doing serious work on calculating water supply needs for fire protection. Hydraulics for the fire service isn’t just the need for water but the need to protect life and property. The person most recognized as the champion of the scientific application of hydraulics to the fire service is Fred Shepherd, considered the father of the fire service. He wrote his first book about hydraulics for the fire service in 1917. The book Practical Hydraulics for Firemen was written for the average firefighter, not engineers. Essential items that use hydraulics in the fire service are standpipe systems, sprinkler systems, engines, ambulances, ladder trucks, etc… We see in the structure of hydraulics we use force and pressure, velocity and flow, gallons per minute, friction loss, pump discharge pressure, and formulas to calculate how many gallons per minute we are pumping out on the fire ground.

HOW HYDRAULICS IS A NECESSITY WITHIN THE FIRE SERVICE 3 Without Hydraulics in the fire service we would not have fire protection, fire protection systems, or the availability of jobs in the U.S. While many things about hydraulics the most important is the fact that it is used to protect lives and properties. Hydraulics will forever be a necessity in the fire service. We have been using Water and Hydraulics since the beginning of the fire service and it is proven that we will continue to use it until something new becomes available. References Crapo, W. F. (2017).
