A proportional controller is implemented in the model to achieve a target flow rate at the pump exits.
A tube from the pump exits the skin and connects to a controller that regulates the function of the pump and to a power source.
For the bicycle pump the invisible features are the inlet and outlet valves and the three phases of movement of air, entering the pump, moving through the pump, exiting the pump.
For such impeller configurations, looking from the pump outlet section toward the twin impellers, the blades of both impellers can be aligned along the exit width or staggered.
Hospital policy, approved by the Infection Prevention Committee, mandates hand hygiene to be performed upon room entry and room exit ("pump in, pump out") using a 63 % isopropyl alcohol-based hand wash or water and antibacterial soap.
The end effect by the magnetic field distortion at the pump entrance and exit caused by the finite core length of the electromagnetic pump, which could result in the decrease of the developed pressure, was analyzed.
Clearly, not anticipated by earlier models were the findings that under some conditions the highest concentration of "hot" (>10eV) hydrogen was found at the gas entry end, and not in the high-field region between the electrodes, and that in other conditions, the hottest H was at the (exit) pump (also grounded electrode) end.
The working volume (overall reactor volume based on the vessel size) was controlled at 1.3 L by means of an overflow tube connected to an exit pump.
The volume of the Douglas bag was measured by a dry gas meter (Harvard, USA), with the aid of a vacuum pump on the exit port.
