- 1. Fluid kinematics is the branch of fluid dynamics that deals with the motion of fluids without considering the forces and pressures that cause the motion. It focuses on describing and analyzing the motion of fluids in terms of velocity, acceleration, and displacement. Key concepts in fluid kinematics include streamlines, pathlines, streaklines, and vorticity. Understanding fluid kinematics is essential for studying fluid flow and predicting behavior in various applications such as engineering, meteorology, and oceanography.
