This widely used fluid mechanics film series, which was produced
at the Iowa Institute of
Hydraulic
Research (IIHR) under the direction of Hunter Rouse, now is
available
in digitized form and are available for download. The files are in MPEG
format, and are ~ 300 MB each, so download times may be long.
Introduction to the Study of Fluid Motion (link to the file)
Designed to orient engineering students, this video shows examples of flow phenomena from a host of everyday experiences. Empirical solutions by means of scale models are illustrated. The significance of the Euler, Froude, Reynolds, and Mach numbers as similitude parameters is illustrated.
Fundamental Principles of Flow (link

Second in the series, this video departs from the essential generality of the first by explicitly illustrating, through experiment and animation, the basic concepts and physical relationships that are involved in the analysis of fluid motion. The concepts of velocity, acceleration, circulation and vorticity are introduced, and the use of integral equations of motion is demonstrated by a simple example.
Characteristics of Laminar & Turbulent Flow (link

The fourth video deals with the effect of viscosity. Dye, smoke, suspended particles and hydrogen-bubbles are used to reveal the velocity field.Various combinations of Couette and plane Poiseuille flow introduce the principles of lubrication. Axisymmetric Poiseuille flow and development of the flow around an elliptic cylinder are related to variation in the Reynolds number, and the growth of the boundary layer along a flat plate is shown.
Instability in boundary layers and pipe flow is shown to lead to turbulence. The eddy viscosity and apparent stress are introduced by hotwire-anemometer indications. The processes of turbulence production, turbulent mixing, and turbulence decay are considered.
