    This report was prepared in the Applied Mathematics Research Branch of the Aeronautical Research Laboratory, Office of Aero-space Research, Wright-Patterson Air Force Base. Viscous flow between two parallel disks, which rotate together at a constant angular velocity is investigated. The fluid enters the space between the two disks and is set in a spiral motion due to friction and centrifugal forces respectively. The pressure will increase with the radius because of the centrifugal forces, thus the arrangement can serve as a centrifugal pump. A mathematical analysis determines the velocity distribution between the disks, the pressures, the torque applied at the shaft and the resulting efficiency.
