Unformatted text preview: degrees Celsius . If a pressure gradient of -10 Pa/m is imposed along the axis, at what speed would the inner cylinder move? 4) Consider a circular pipe with area .01 m 2 and a slender rectangular duct with height .01 m and width 1 m. Assuming the same pressure gradient is applied to each, which one will pass more fluid? What is the ratio of volume flow rates? (Assuming laminar flow in both pipes. You may neglect end effects in the rectangular duct). 5) Consider a circular pipe 3 m long, 1 cm in radius. The gage pressure at the inlet of the channel is 1.1 atm. The outlet is at atmospheric pressure. In one minute you collect 6 liters of fluid. Assuming you have fully developed laminar Poisseuille flow from inlet to outlet, what is the viscosity of the fluid (in Pa-s)?...
