Problem 6.80

Two immiscible, incompressible, viscous fluids having thesame densities but different viscosities are contained between twoinfinite, horizontal, parallel plates (Fig. P6.80). The bottom plate isfixed, and the upper plate moves with a constant velocity U.Determine the velocity at the interface. Express your answer in termsof U, 1, and 2. The motion of the fluid is caused entirely by themovement of the upper plate; that is, there is no pressure gradient inthe x direction. The fluid velocity and shearing stress are continuousacross the interface between the two fluids. Assume laminar flow.

Intro to Anthropology Intro to Anthropology Lecture One  Anthropology studies human society from two perspectives:  Diachronic view: stresses development through time  Synchronic view: emphasizes the contemporary state of human societies with little or no time depth  The four subdisciplines of anthropology Physical/ biological anthropology  The study of human biological evolution and variation between living populations  Human biology/ biological anthropology - contemporary studies of comparative variability (present time, synchronic aspect)  Human paleontology - paleoanthropology - comparative studies of fossil remains (past, diachronic)  Primatology - the study of both living and extinct species Cultural anthropology  Emphasis is behavior, with two approaches to the study of living societies 1.) Ethnography: descriptive study of human societies throughout the world (who, what, when, where)  Explorers, missionaries, traders, soldiers  Trained anthropologists  Participant/observer Linguistic Anthropology - Language  Structural linguistics (synchronic): the systematic study of the component parts of languages and their relationship - Phonology = sounds - Grammar = rules - Syntax = arrangements - Semantics  Historical linguistics - how languages developed, an
