"Webb12 okt. 2024 · The stoichiometric number, λ, is defined as the ratio of the actual flow rate to theoretical flow rate. Figure 7 shows that as the stoichiometric number increases, the charge-discharge cycle time increases. The extension of the cycle time can be explained as the increase in capacity of the VRFB, which means that the battery can store more energy. " - Theoretical flow time formula

WebbAlthough usually we report tr and w using units of time, we can report them using units of volume by multiplying each by the mobile phase’s velocity, or in linear units by measuring distances with a ruler. For example, a solute’s retention volume, Vr, is Vr = tr × u where u is the mobile phase’s velocity through the column. Webb= bottoms flow rate (mole time -1) = heat capacity of liquid water (energy mole -1 temperature -1) or (energy mass -1 temperature -1) = distillate flow rate (mole time -1) = stage efficiency (unitless) = liquid flow rate in the rectifying section (mole time -1) = liquid flow rate in the stripping section (mole time -1)
