Lead-acid batteries remain popular because of their capability to seiwice high and low current demand, produce high voltage, provide capacity up to 100 A-h, and recharge well. Moreover, the lead-acid battery has important material and construction advantages, such as simple fabrication of lead components, the low cost of materials (lead is abundant and much less expen-... 

In recent years, much attention has been devoted to improving the efficiency with which energy is produced and used by society in general and also in chemical manufacturing. Higher fuel efficiency in automobiles, better insulation materials and construction practices for homes, and energy efficient lighting and ap-... 

Use only chemical protective clothing that has undergone material and construction performance testing against arsenic vesicant agents. Reported permeation rates may be affected by solvents, components, or impurities in munition grade or modified agents. 

Not an exhaustive list of ISE electrodes or number of interferences. Also, manufacturer specifications must be consulted as different materials and construction may result in different ranges and interferences. 

UL 2085, Protectedf Aboveground Tanks for Flammable and Combustible Liquids, covers shop-fabricated, aboveground atmospheric protected tanks intended for storage of stable, flammable or combustible liquids that have a specific gravity not greater than 1.0 and that are compatible with the material and construction of the tank. 

Check that material and construction conform to specification.

When metal apparatus is designed for chemical applications, it is usually necessary to consider corrosion and heat resistance as well as ease of fabrication. In this appendix these topics are discussed at a level which should help the experimentalist to specify the correct materials and construction procedures. No details of shop practice are given. The interested reader may pursue this topic in the general references cited at the end of this appendix, and in Chapter 10. 

To create a work of art in three dimensions, the artist has a choice of materials and construction methods. Three-dimensional pieces can be constructed by adding material to create a form, or by removing material to reveal a form. These two methods represent the... 

In principle, material selection, cable design, and installation method can work together to produce the solution for meeting performance requirements within standards. However, in many cases the standards have evolved based upon certain materials and constructions, thus limiting material selection options unless one is willing to propose changes to standards, which is a lengthy proposition. 

Coopers, 2006 Worldwide Fuel Cell Industry Survey, 2006). Nevertheless, cost projections for AFCs can present a more optimistic picture, in the case of evolvement of the basic materials and construction techniques results in lower manufacturing costs (Staffed et al., 2007 McLean et al., 2001 Gtilzow et al., 2004).

Plant layout is one area where real cost control can be exercised because of the impact on material and construction costs as well as on operating efficiency. The final layout, usually developed during the basic engineering stage, requires a high degree of experience and the participation of the entire project team as well as the contractor s specialists and Owner s operations and maintenance personnel. 

To determine the change in pump efficiency for a given seal size, material and construction, a coyistant difference in horsepower should be used, not a constant decrease in points of efficiency (rj). Fig. 4 shows pump horsepower at operating conditions vs. loss of efficiency when using double mechanical seals. (Fig. 4 is to be applied to pumps that have been tested at 1,750 or 3,550 rpm.)...
