Jin Feng did three simulations of the bottle assembly and verified that reducing the mid cap height results in increased outlet air flow. If the bottle base and two electronics compartments are removed, reducing the mid cap height from 66mm to 43mm increases the outlet velocity from 4.12m/s to 4.99m/s. With the addition of the bottle base and two electronics compartments in our current design, the outlet velocity is reduced to 3.88m/s, which is still a refreshing breeze of air.
