The values for pressure ratio in a practical case must include allowance for pressure drop in the interstage piping. In the sizing procedure used by manufacturers, certain adjustments must be made to the ideal for incremental cylinder sizes and allowable rod loading. Efficiency is represented by r. yi. 

Aside from the efficiency of the motor itself, energy efficiency is very dependent upon proper sizing. While the efficiency of a motor is fairly constant from full load down to half load, when a motor operates at less than 40 percent of its full load, efficiency drops considerably, since magnetic, friction, and windage losses remain fairly constant regardless of the load. Moreover, the power factor drops continuously as...

Power plant boilers with full heat recovery and utilizing high-grade coal in the form of pulverized fuel (PF) tend to provide the highest full load efficiencies, at 85 to 90%. 

Figure 7.6. When a force is applied to a bone of uniform structure (a), the structure adapts by the feedback mechanism shown in Figure 7.5 and forms a nonuniform structure to carry the load efficiently (b). The resulting structure resembles the familiar design of bridges and other man-made trusses (c).

Working load. The efficiency drops off quickly as the load decreases. The more the load is decreased from 100% rated capacity, the steeper is the decline in the machine performance. The decline in performance depends on the machine and the control system. For example, at 70% of full load, the ratio of the part-load efficiency to the efficiency at full-load might vary typically between 0.95 and 0.85, depending on the machine and the control system. Twin-spool machines have a better part-load performance than single-shaft machines. Part-load performance depends on the size of the machine.

Explosive, Canadian. An aqueous slurry of AN and TNT, developed by Canadian Industries Ltd in collaboration with inventors M.A. Cook and H.E- Famam has been used for open pit blasting at Iron Ore Co of Canada s Knob Lake operations in Newfoundland. The fluid character of the material enables it to be loaded efficiently into bags or directly into the borehole without a container. Because of its high density (1.4) and good water resistance, it. can be loaded... 

The water-in-oil-in-water (w/o/w) emulsion method (Figure 11.4) is the predominant method used for encapsulation of biomacromolecules in these microparticles. Protein solution forms the internal water phase of the w/o/w emulsion. Loading efficiency of the microparticles has not been optimal using water or buffer as an internal phase, so water is sometimes substituted with polymeric liquids, such as low molecular weight polyethylene glycol. The primary emulsion is then added to a secondary liquid phase, forming the secondary emulsion. The solvent for the...
