Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. In fluid power, hydraulics is used for the generation, control, and transmission of power by the use of pressurised liquids. This book discusses hydraulic mechanical applications and roles in engineering. Topics include axial piston pumps; turbulence structure and related mass transfer mechanisms in vegetated canopy open-channel flows; the hydraulic mechanism features of jet-curtain operation; experimental design and calibration of grid gates used in open channels;...
