, mR = inside capillary tube radius, mL = capillary tube length, mFor a laminar, incompressible, Newtonian fluid, the shear rate at the circular pipe wall,γ wall can be calculated from the microscopic balances4. The result is shown below.γ wall = (4Q)/(πR3) = (32Q)/(πD3) 8V/D= 4V/R (2)Where: Q= volumetric flow rate, m3/sV= average fluid velocity, m/sThe Hagan-Poiseuille equation can also be calculated from the microscopic solution forthis problem4, and may be used to calculate the viscosity of a laminar, Newtonian,incompressible fluid ∆PR 2V = (3) 8µLThe equations for Reynolds number and entrance length2, Le

. Thework-load for the grader was quite extensive and timing became difficult to track based upon theamount of information exchanged. This process was improved by posting the reviews and therebuttals on the actual article, but the grader’s handling of paperwork was still quite extensive.The Public Knowledge Project has an Open Journal System that has been developed to improvethe review process (http://pkp.sfu.ca/?q=ojs). In the future this system may be used to helpfacilitate the review process.Continuing DevelopmentWhile this approach can be adopted for different courses, one issue with this technique is thelack of exact repeatability in the same course. Future students will not be starting from scratch inwriting the wiki textbook as the first set

flexibility, i.e., it must have a sufficient number of manipulated variables that must belocated so that the objectives can be achieved. The selection of the proper manipulated variablesis not obvious, so that students should be taught to rely on fundamentals and innovation whenproviding flexibility. A nice example is adjusting the distillation condenser for control pressure.Flexibility analysis builds on the design equation, Q = U A (∆T), which shows that flexibility ispossible by adjusting (1) the heat exchanger area (A), (2) cooling temperature (∆T), or (3) thecoolant flow rate (U and ∆T). Each of these approaches is used in practice, with the proper
