INTRODUCTION TO
SECOND EDITION
According to Webster's Dictionary, hydraulics is that branch of
science or engineering which treats of water, or other fluids, in motion
and the works and machinery for conducting or raising it. Fire
Service Hydraulics fits this definition except that it deals only with
water and its various applications, including foam, and certain spe•
cialized machinery and equipment that includes hose and nozzles.
Fire Service Hydraulics also includes the action of the men who
manipulate this water and machinery. It is therefore a unique
branch of hydraulics that has been tailored to a unique service and to
the men who provide it-fire fighting and fire fighters.
We have divided this Second Edition of Fire Service Hydraulics into
four parts: Theory, Water, Practice and Foam.
Part I-Theory, includes two chapters and was written by Robert
L. Darwin. It could almost be called an introduction to fluid
mechanics. In the first chapter, Mr. Darwin covers the physical laws
relating to Hydrostatics (fluids at rest) and ics (fluids in
motion). In the second he covers the relationships that control the
performance of water when it is used in the typical fire fighting
