Abstract

The prime objective of this text is to describe the elementary concepts involved in laminar fluid flows. In general, any flow is characterized by the continuous deformation of fluid particles and a corresponding internal state of stress. It has been experimentally established that, under laminar situations, the rate of deformation is directly proportional to local viscous stress. Laminar flows thus fall under the category of viscous flows. The principle laws that govern the motion of fluids are also discussed.
