"Hydraulics and pneumatics play a pivotal role in shaping the design, maintenance, and optimization of systems responsible for managing water and air resources. Hydraulics, with its focus on the behavior of fluids at rest or in motion, is integral to projects like water distribution, wastewater treatment, and flood control. Pneumatics, centered on the properties and applications of compressible gas, informs designs of air pollution control systems and aids in understanding gas exchanges in natural ecosystems. Together, these disciplines ensure that environmental engineering solutions are efficient, sustainable, and responsive to the unique challenges posed by natural and built environments."-- Provided by publisher.
