Basic concepts and physical relationships
of fluid motions
Flow
patterns – velocity vectors, streamlines, pathlines,
streaklines –, local and convective acceleration,
relative motion, continuity relationship, vorticity,
circulation, rotational and irrotational flow, flow net
(0:00 to 10:40)
Flow dynamics
Flow
acceleration and pressure-velocity relationship for
non-uniform states of motion, dynamic and static
pressure, principle for simple instruments for the
measurement of velocity, pressure and rate of flow,
separation, cavitation, integration of the continuity,
momentum, and energy equation, propulsion
