Rated capacity, defined

The maximum safe load is shown as the RATED CAPACITY defined by a weight and distance, e.g. 1000 kg at 500 mm load centre, or 2240 lb at 20 in load centre. The load centre is measured from the heel of the forks to the... 

The resin beads used in most columnar operations range in size from 0.3 to 0.9 mm in diameter, which is a compromise based on the effect of ion-exchange rates, capacities, and hydraulic characteristics. The especially made resins used in resin-in-pulp operations range in size from 0.8 to 1.6 mm in diameter. The apparent density of a resin is defined as that weight of backwashed and settled wet resin per cubic foot, which for resins used in the uranium industry is about 38-45 Ib/ft . In column operations, the attrition losses due to swelling and contraction of resin, abrasion of resin-resin surfaces, and abrasion of resin-equipment surfaces are negligible. In resin-in-pulp operations, an appreciable amount of attrition loss is encountered. 

One issue is how to define the capacity of a fully charged battery. It can be the rated capacity (given by the manufacturer), the measured capacity (which changes with age), or the practical capacity (battery capacity that is available during operation conditions). The differences between these capacities is illustrated in Fig. 8.7. Definitions of SoC, SoH, measured capacity, practical capacity etc. are given in Table 8.1. A detailed discussion of these terms has been presented by Sauer et al. [4]. 

The SoH is defined as the quotient of the measured capacity and the rated capacity. The measured capacity is the capacity of a fully charged battery at standard discharge conditions. In some applications (e.g., automotive), the high-power capability is of interest. Therefore, other definitions for SoH are also possible. 

Here 8766 is the average number of hours per year, K is the rated capacity of the power plant in electric megawatts, and T is the number of years between the start of an irradiation cycle and the time the reactor is shut down for refueling. L is the availability-based capacity factor, defined as the ratio of the amount of electricity generated by the power plant when not shut down for refueling to the amount it could have generated if operated at capacity for the same time.

The moisture characteristic (moisture content versus soil suction) of a soil provides valuable data concerning the moisture contents corresponding to the field capacity (defined in terms of soil suction, this Is a pF value of about 2.0) and the permanent wilting point (pF of 4.2 and above), as well as the rate at which changes In soil suction take place with variations in moisture content. This enables an assessment to be made of the range of soil suction and moisture content that is likely to occur In the zone affected by seasonal changes In climate. 

Each type of rigging can carry some defined load. A rope of a certain diameter has a rated capacity based on ultimate strength and a factor of safety. Chapter 10 discussed factors of safety for materials. Various factors reduce the... 

Eiaving estabiished the overfiii ievei (maximum capacity), it is then necessary to specify a ievei beiow this that wiii aiiow time for any action necessary to prevent the maximum from being reached/exceeded. This is termed the tank rated capacity , which wiii be iower than the actuai physicai maximum. Reference shouid be made to Appendix 3, Guidance on defining tank capacity for a definition of these terms. 

The nominal capacity of valve-regulated batteries is defined between I5 and I20 according to the application and the technology of the battery. For definition the rated capacity following discharge rates is valid at T = 20°C ... 

Cycle life Cycle Ufe is the most critical performance parameter and is defined as the number of cycles delivered by a rechargeable or secondary battery before the battery s rated capacity falls to 80% of the initial capacity in a particular application. 

The cycle life characteristics of traction batteries are presented in Figure 1.28. This figure shows the relationship of cycle life to DOD at the 6-h discharge rate, cycle life being defined as the number of cycles at 80% of rated capacity. It is quite... 

The primary failure mode of the VRLA battery can be defined as growth of the positive plate. Because this growth is the result of chemical reactions within the cell, the rate of growth increases with increasing temperature. In Fig. 24.20 the float life is plotted against temperature. The solid lines represent data from float-life tests performed at two float voltages, 2.3 and 2.4 V per cell. This graph can be used to determine the expected float life at various temperatures. End of life is defined as the failure of the cell to deliver 80% of rated capacity. 

The probability of finding the generator in the forced outage at distant time in the future represents the basic parameter used in static capacity evaluation for modelling of generating unit reliability. This probability is defined as unit Unavailability (U) and in power system applications it is known as the unit Forced Outage Rate (FOR), defined as ...
