Exterior Design Considerations

Like other industries, car companies do care about their consumers. Apart from obvious price considerations, consumers do have needs and expectations. These needs and expectations concern not only technical specifications linked to the performance of the car (top speed, fuel consumption, safety, etc.) but also subjective aspects, such as the aesthetics of the exterior design. With both of these, there is room for sensory science, because many aspects involve the sensory perception of the car. 

Pasquariello [ 160] has reviewed the requirements for efficient and safe handling of caustic and presented design considerations for storage and piping systems. Caustic soda and potash are most frequently stored in carbon steel tanks. The exterior of such tanks should... 

This chapter addresses blast resistant considerations for doors, windows, utility openings, and special exterior and interior requirements. These considerations should be jointly addressed by the building design team. 

Upon removal from their package, all these devices present common exterior surfaces. On one side, they have an impermeable backing layer across which neither the drug nor any other component can diffuse. On the other face which will contact the skin, there is a peel strip which is removed prior to application. In between these two layers, however, the composition and design of the device varies considerably. 

An important consideration in designing dies and tips for wire coating is draw-ratio balance (DRB) defined by Eq. (6.4). The ideal value of DRB is 1, which means that the interior and exterior surfaces of the tube are drawn to the same extent. For FEP and PFA, the DRB range is 0.9-1.15. Concentricity suffers at DRB <0.9 while a DRB >1.1 can result in tears. ETFE has a more narrow range, 1.04-1.07. Drawdown ratios for large diameter cables may range from 2 1 to 3 1. 

Separation procedures must be designed with kinetic considerations in mind -- adsorption from a stream of gas is not an instantaneous process. It was stated earlier that the adsorptive capacity of charcoals does not depend on particle size, but it is expected that rates of adsorption will be so dependent. A reduction in the average particle diameter increases the exterior surface (per gram adsorbent), presented to the gas phase and shortens paths through cracks and pores along which adsorbate molecules must diffuse in order to reach adsorption sites in the particle interior. Approach to equi-...
