WebFigure 8 depicts the effect of air flow velocity on the current density of a single Zn–air fuel cell. Regarding air serving as the oxidant gas, an increase of the air flow velocity might have led to the increase of the current density (and cell performance) in the flow velocity, which ranged from 0.01 to 0.5 m/s. WebAug 4, 2024 · More succincty: Steady flow means that at each position in the system, the density pressure, and velocity aren't changing. But a fluid element will move around the system, so its density, pressure, and velocity will vary as it moves. At time 2:01 he says Density is NOT a function of time. ingleby barwick windows
