Size relative capacity factor

These scale-up factors are relative capacities of centrifuges of the same type hut different sizes when performing at the same level of separation achievement (e.g., same degree of clarification). These factors must not he used to compare the capacities of different types of centrifuges, f Approaches 2.5 at rates helow mL/min. fLong howl configuration. 

It was recently reported that the application of a protective polarization may be avoided by using corrosion-resistant activated electrodes [32], The polarization protection of the electrodes represents approximately 1-2% of the nominal electrolyzer power. Assuming the capacity factor of the electrolyzer cannot exceed the one of the wind turbine, the polarization protection should be applied during 60% of the electrolyzer s lifetime or higher depending on the relative sizes of the electrolyzer and wind turbine. 

RAW MATERIAL PANEL SIZE A Standard panel size related to machine capacities, raw material sheet sizes, final product size, and other factors. register mark A mark used to establish the relative position of one or more printed wiring patterns, or portions thereof, with respect to desired locations on the opposite side of the board. 

Fuel cell system for individual user (residential or commercial) sized to cover the entire load. Such a system would have a low capacity factor and relatively low average efficiency, and because of that, the payback time will be unacceptably high. Nevertheless, this scenario may be acceptable where the user is willing to pay premium price for being grid independent. In addition, this may pass in the new homes market, where the buyer pays for an oversized and not very efficient fuel cell, but the high cost is masked by the cost of the entire purchase. 

Capacity requirement is a prime factor in conveyor selection. Belt conveyors, which can be manufac tured in relatively large sizes to operate at high speeds, deliver large tonnages economically. On the other hand, screw conveyors become extremely cumbersome as they get larger and cannot be operated at high speeds without creating serious abrasion problems.

The solvent triangle classification method of Snyder Is the most cosDBon approach to solvent characterization used by chromatographers (510,517). The solvent polarity index, P, and solvent selectivity factors, X), which characterize the relative importemce of orientation and proton donor/acceptor interactions to the total polarity, were based on Rohrscbneider s compilation of experimental gas-liquid distribution constants for a number of test solutes in 75 common, volatile solvents. Snyder chose the solutes nitromethane, ethanol and dloxane as probes for a solvent s capacity for orientation, proton acceptor and proton donor capacity, respectively. The influence of solute molecular size, solute/solvent dispersion interactions, and solute/solvent induction interactions as a result of solvent polarizability were subtracted from the experimental distribution constants first multiplying the experimental distribution constant by the solvent molar volume and thm referencing this quantity to the value calculated for a hypothetical n-alkane with a molar volume identical to the test solute. Each value was then corrected empirically to give a value of zero for the polar distribution constant of the test solutes for saturated hydrocarbon solvents. These residual, values were supposed to arise from inductive and... 

With regard to specific types of equipment, the safety factor practices of some 250 engineers were ascertained by a questionnaire and summarized in Table 1.4 additional figures are given by Peters and Timmerhaus (References, Section 1.1, Part B, pp. 35-37). Relatively inexpensive equipment that can conceivably serve as a bottleneck, such as pumps, always is liberally sized perhaps as much as 50% extra for a reflux pump. In an expanding industry it is a matter of policy to deliberately oversize certain major equipment that cannot be supplemented readily or modified suitably for increased capacity these are safety factors to account for future trends.
