MAJ Mower is an Engineer officer with tactical and operational experience in multiple units which participated in three deployments in support of Operation Iraqi Freedom, and one for Operation Atlantic Resolve. Her most recent assignment was as the 553rd Engineer Detachment/Forward Engineer Support Team – Advanced (FEST-A) Commander that is part of the U.S. Army Corps of Engineers’ North Atlantic Division, New York District. Specifically, the 553rd ensured the provision of multi-functional technical engineering capabilities such as: limited engineering design; engineer reconnaissance; construction planning and management; base camp development; and geospatial, construction contract, security engineering, and USACE engineer reach-back support. Previously, she served as the 169th Engineer Battalion Executive and Operations Officer over five companies and two detachments within TRADOC that trained 3,500 Soldiers and Non-Commissioned Officers as well as 1,200 Sister Service personnel in over 300 classes per year at five different geographic locations. Her research interests include the how environmental policy, both at the international and domestic levels, results from or intersects with environmental technologies. MAJ Mower teaches EV350 and EV450, required courses for cadets in the environmental engineering sequence.

Abstract

Gravity-fed water supply systems are vital in providing much of the developing world clean water. To correctly design and implement gravity-fed water systems, engineering students should understand both the continuity and energy equations. However, instead of trying to explain the often-challenging energy equation solely through the use of textbooks or PowerPoint presentations, a simple in-class demonstration can illustrate the relationships between the elevation head, pressure head, and velocity head terms. A solid understanding of these relationships will help cadets determine the hydraulic head of a system at any given point by developing a Hydraulic Grade Line (HGL), which is used to understand capabilities and constraints of a gravity fed system.
