Films on Youtube (six films) Introduction to the study of fluid
motion (1961, 25 minutes) http://youtu.be/EIuU9Q8CGDk The first
in a widely used series of films on fluid mechanics, produced at
IIHR under the direction of Hunter Rouse. This introductory
program, designed to orient engineering students, 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. Dr. Hunter Rouse served as
Director of IIHR from 1944 to 1966. During this time, he was
instrumental in strengthening IIHRs fundamental research
emphasis and in developing teaching programs for hydraulic
engineers. Through his writings, research, and global travels,
he established IIHR as an intern
