Topics will include sensing platforms, devices and instrumentation, biomolecular engineering of probe molecules, quantitative evaluation and comparison of biosensors, design trade-offs and private sector considerations (markets, intellectual property, FDA requirements and approval process, translational process). In tube flow with mass transfer at the wall, one expects that the time-smoothed concentration CA will vary only slightly with position in the turbulent core, where the transport by turbulent eddies predominates.

The same can be done for any geometry and for both laminar and turbulent flow. Complete details will be presented in the next section. 10.2.8 Pipe Fittings and Valves In general, any time the velocity profile in a pipe is disturbed, there is an increase in the pressure loss, as compared to a straight pipe of equivalent length. Non – Equilibrium and ∆P= Driving Force.  When the two tanks reach the same pressure. Development of the steady-state temperature pro- file for a solid slab between two parallel plates.

From that point on, the asymptotic solution, valid for large z only, proceeds as in s10.8. Here to a first ap- proximation it may be assumed that the two species react so rapidly that they cannot coexist. The transition from bubbling or slugging to turbulent fluidization can be estimated by [Yl] v, = 7.0(psd,)‘n - 0.77 (12.100) where V, is the transition velocity (m s-l) and p,d, is the solids density times mean diameter (kg m-‘). Therefore we must have an expression more general than Eq. 1.1-2, but it must simplify to Eq. 1.1-2 for steady-state shearing flow.

A pebble heater is a fixed-bed device used to heat steam and/or other gases to temperatures higher than could be obtained in units solely fabricated of metal. A small-scale piping system (diameter 0.025 m, length 0.25 m) gives the following results for a non-Newtonian fluid: If the pressure drop in a 0.03-m-diameter pipe is limited to 13.8 x los N/m2 at a volumetric flow rate of 6.26 x 10-5 m3/s, what length of pipe is needed? 4-17. Examines social and humanistic aspects of using current and future technology to understand and solve environmental problems.

The void fraction is the ratio of the free volume to the total volume: &= V total - v, V total where VP is the total volume of all particles. Tubular Exchangers Manufacturers Association: Star&& of the TEMA, 6th ed., TEMA, New York, 1978. This is true for flow into a channel, and, in fact, Fig. 4.3-5 was obtained in this way.9 For other systems, such as the flow around the cylinder, the separation point and separa- tion streamline must be located by experiment.
