External flow occurs over surfaces, internal flow is completely bounded, open-channel flow is partially filled. Incompressible flow maintains nearly constant density, compressible flow varies significantly. Boundary layer forms when fluid encounters stationary solid surface. Steady flow involves no changes with time, unsteady flow involves changes
EAGLE is a professional PCB design software by Autodesk Inc. Program consists of four main components: circuit diagram, PCB editor, tracing, and library. Maximum board size is 1600/1600 mm with 16 layers. Includes extensive component library with templates and mock-ups
Chemical engineering evolved from industrial applications of chemistry and separation science. First high-volume chemical process implemented in England in 1823. American Institute of Chemical Engineers formed in 1908. Nomographs developed in 1930s-1940s for process analysis. Computer-aided design became commonplace in 1970s
Born in 1932 in Newark, New Jersey to Jewish parents. Graduated from Cornell University with architecture degree. Became part of New York Five architects in 1969. Currently teaches at Yale School of Architecture
Automotive design develops appearance and ergonomics of various vehicles. Design teams typically consist of 25-40 members working over 24 months. Design focuses on form-function combination from vehicle package
