Abstract
An improved centrifugal pump uses straight tubes or fluid channel members rather than expanding passages between the inlet and exit flow. In straight tubes a process occurs of building up of pressure faster than within the passages as the fluid attempts to expand due to the Coriolis force potentially acting against the centrifugal force to build up the pressure within and along the tube or fluid channel. Because the flow increases faster than increases in RPM a more compact pump is provided that can move more air and produce higher pressures than ordinary centrifugal pumps. Hence: 1) Flow increases proportional to tube area because a larger area means more air can be drawn into the tube; 2) Flow increases proportional to tube length because the exit pressure increases proportional to tube length; and 3) Flow increases faster than increases in RPM, thereby exhibiting a higher outflow pressure.
