hydromechanics
Water motion science
Hydromechanics is the branch of physics dealing with the motion and behavior of fluids, particularly liquids.
The term encompasses both hydrostatics (fluids at rest) and hydrodynamics (fluids in motion).
Engineers apply hydromechanics to design pumps, turbines, and hydraulic systems: The dam's spillway required careful hydromechanics calculations.
