Pack sizes

Numbers on lines represent G values = gas flow in kg/(m -s) = nominal packing size = superficial velocity. To convert kg/(m -s) to lb/(h-ft )... [Pg.34]

An advanced Li—Mn02 battery under the trade name MoHceh has been developed by MoH Energy Ltd. (49). The cell has a nominal voltage of 3 V, allowing replacement of two NiCd cells with one MoHceh, hence significantly reducing battery pack size and volume. Production "AA" cells demonstrate a nominal capacity of 600 mAh for an energy density of 100 Wh/kg. Cycle life for this cell is reported to be typically 200 cycles (50). [Pg.584]

The term Fp is a dimensionless dry packing factor, specific for a given packing type and size. Values of Fp are given in Table 14-7. For operating pressures above atmospheric, and for certain packing sizes, Lj and Gj a.re calculated differently ... [Pg.1388]

The number of packing sizes, types (designs), and materials of construction currently available to the designer has increased considerably. To select a packing for a process application requires a weighing of information and an evaluation of the closest comparable data. [Pg.276]

As a guide with only rough experimental backing, the ratio of maximum random packing size to tower diameter is... [Pg.280]

Often it is only necessary to change a packing size or type to modify the capacity and/or contacting efficiency... [Pg.290]

Packing size versus tower diameter recommendations general guides not mandatory, base selection on performance. [Pg.297]

Table 9-27 shows what Strigle [82] recommends for the maximum liquid loading as related to packing size. [Pg.297]

Establish tower diameter Robbins [96] recommends that the tower diameter should be at least 8 times the packing size if not, repeat the calculations with different packing. [Pg.298]
