Hydraulic design

Definition

Hydraulic design refers to the engineering process of designing systems that manage and control fluid flow within various structures, ensuring optimal performance and efficiency. This includes consideration of factors like fluid dynamics, pressure drops, and the physical characteristics of materials used in constructing components such as columns in separation processes. Proper hydraulic design is crucial for achieving desired operational results in systems involving fluid transport and processing.
