Pressure Driven Flow In A Pipe

A Microfluidic-based Hydrodynamic Trap: Design And Implementation
The flow rate through the outlet channel with the constriction (Q c) to the total flow rate (Q tot = Q c + Q n) as a function of the constriction width (w c) and length (L c). We assume that the flow is pressure-driven from a common source and the outlet channels * To whom correspondence should be addressed: cms@illinois.edu. ... Read Full Source

FLOW IN PIPES - Kau.edu.sa
Fluid flow is classified as externaland internal, depending on whether the fluid is forced to flow over a surface or in a conduit. Internal and external flows exhibit very different characteristics. In this chapter we consider inter-nal flowwhere the conduit is completely filled with the fluid, and flow is driven primarily by a pressure difference. ... Access Full Source
